Chapter 350 Overload Test! (Added update 3/3 for Mo Ruixue)
Chapter 350 Overload Test! (Added update 33 for Mo Ruixue)
"Reporting to the chief, the prototype has undergone four thirty-five dynamic tests, and all test items have passed successfully. It is currently undergoing a load test. According to the chief engineer's plan, this is the last test item of the prototype's dynamic test." The person in charge was outside the crowd.
The guard recorded in the test project briefly introduces the basic situation and progress of the current dynamic experiment.
"Fortunately, we have caught up, and this meal is quite hot." Chen Kang, who arrived late, listened to the guard's report on the test situation, nodded slightly, looked at the Red Star tractor that was loading items, and turned to
Li Qiang, who was standing beside him, joked: "Youfan, judging from your experience in the Soviet industrial field, how much do you think the Red Star tractor can pull?"
Chen Kang had not participated in the first few dynamic tests at the proving ground before. His task was to stay at the headquarters to greet Li Qiang. Who would have thought that when Li Qiang arrived at the headquarters and learned about the dynamic tests of the prototype, he immediately asked to come over. Chen Kang
Unable to resist, he had no choice but to accompany him and hurried to Liushugou.
Fortunately, I hurried slowly and hurriedly, and finally caught up with the dynamic test of the prototype car that was coming to an end.
"I have not been deeply involved in the field of power machinery, but I have some understanding of the automobile industry. Based on military truck standards, I think this Red Star tractor has a maximum load capacity of 1.5 tons. Considering that the base area has never had power machinery production experience and technology,
The actual level can reach the 1-ton level, which is considered very good." Li Qiang's eyes were fixedly watching the Red Star tractor being loaded through the electric hoist in the loading and unloading area, his eyes were full of curiosity, he pondered for a while, and slowly gave his own explanation
judge.
1 ton!
Although this load capacity is not very eye-catching, for a tractor, it is really excellent. You know, even the military trucks of many countries have a load capacity that mostly hovers between 1.5 tons and 2 tons. As an industrial power, the Soviet Union
, currently only three-ton trucks have been developed.
"What if I told you that this little guy can pull ten tons?" Chen Kang said with a smile.
"Ten tons?! Impossible, this is absolutely impossible. How can a twelve-horsepower diesel engine pull ten tons?" Li Qiang was stunned for a moment, as if he had been hit by a sap on the back of his head, and his head was dizzy.
He came back to his senses in two seconds, frowned, and immediately said seriously: "Although I major in communications and radio, I still have common sense in these aspects. Old Chen, there is no point in lying to me like this. We must pay attention to following science when engaging in military industry.
Laws and reality.”
Through the information reported by the guard just now, Li Qiang had a basic idea of the general performance of the Red Star tractor. It uses a 12-horsepower diesel engine, a hand-operated mechanical control, and a top speed of 30 kilometers per hour.
A tractor with 12 horsepower can pull 10 tons?
How can this be?
If this is true, where does the GIS-5 military truck that the Soviet Union has just developed put its face?
This thing is the latest military truck developed and put into production by the Soviet Union. It has a load capacity of three tons and has 73 horsepower!
Their 73-horsepower engine can only pull three tons, and it can only pull about two tons on dirt roads and in the wild. Your 12-horsepower engine can actually pull ten tons.
Li Qiang said he couldn't believe it.
"Why am I lying to you? I'm just stating a fact. Professor Zhuang's achievements in the field of mechanics and Yu Hua's talent in the fields of mathematics and mechanics are no less than you who have achieved top scientific research achievements and honors at the Moscow Academy of Communications Sciences in the Soviet Union.
"When Chen Kang heard this, he laughed and shook his head. He looked into the eyes of Zhuang Qianding and Yu Hua in the testing ground, full of respect, and said unhurriedly: "Seeing is believing, just watch carefully."
Others may have doubts about the ten-ton load capacity, but Chen Kang did not. He saw with his own eyes that Professor Zhuang and Yu Hua developed various advanced technologies step by step, leading the Military Industry Bureau to develop to what it is today.
Gray cast iron technology, vertical deep hole drilling machine, manual lathe, two-roller cross-rolling mill, conveyor belt system, crusher, air separation equipment, 2-ton oxygen blowing furnace...
It can be said that without Yu Hua and Zhuang Qianding, the current achievements of the Military Industry Bureau would not have been possible.
Of course, when it comes to contribution, another person has to be involved, and that is Mr. Zhang San. Without the German-made mechanical processing equipment donated by Mr. Zhang San, it would be difficult for the Military Industry Bureau to develop so quickly.
"..."
Li Qiang frowned and wanted to say something, but didn't know how.
As a long-time friend, he certainly understands Chen Kang's character. Chen Kang never tells lies, let alone lies.
Ten tons, can it be achieved?
Li Qiang suddenly felt that he didn't know how to express himself.
At the loading and unloading point of the test site, two soldiers controlled an electric hoist to continuously lift a steel weight of 100 kilograms of reference weight into the container. The load test was divided into three contents: standard load, overload, and ultimate load.
The content of the standard load test is very simple. The tractor is required to carry one ton and reach the maximum speed for ten minutes.
The overload test is not limited to weight and speed. It can pull as much as it can, and the speed only needs to be slightly faster than a person walking.
As for the ultimate load, it is mainly to verify whether the ultimate load of the body structure reaches the standard. The theoretical ultimate load of the Red Star tractor is as high as fourteen tons.
The current test content is the standard load. A weight of 100 kilograms like this needs to be transported for ten yuan.
Five minutes later, ten weights were installed on the prototype vehicle, and the load capacity reached one ton. Then the driver Tao Fang restarted the horizontal-bar diesel engine.
"Thud, tug, tug..." A familiar and rhythmic mechanical melody played again and spread throughout the testing site. Tao Fang sat in the open cab, holding the handle of the tractor's head with both hands, and started shifting gears on a familiar road.
"Buzz..." Accompanied by the roar from the twelve-horse horizontal-bar diesel engine, the high-torque transmission system amplified the power, and the entire prototype vehicle dragged a ton of weights and ran briskly, and the pace was less light than before.
, a little more stable.
Shift gears, accelerate.
The prototype vehicle pulling a heavy load speeds along the circular driveway, traveling faster and faster.
"Bah bang bang!" Applause from everyone in the viewing area came as promised.
"It really started running. It looks very easy." Li Qiang clapped his hands and looked at the Red Star tractor that was continuing to drive. He was full of excitement. The doubts about the load capacity of the Red Star tractor in the back of his mind disappeared, leaving only
Definitely, there is still a little bit of hope.
It's so easy to pull one ton, maybe it can really pull ten tons?
Of course, Li Qiang is not absolutely pursuing ten tons, but if he can pull three or four tons in the next overload test, that would be very good.
"Report, the speed of the prototype is 8.3 meters per second, and it has reached the maximum speed of 30 kilometers per hour." After a few dozen seconds, the timekeeper spoke quickly and excitedly, suppressing the joy in his heart, and reported to Yu Hua, the chief engineer.
Real-time dynamic speed of prototype vehicle.
"Okay, continue monitoring." Yu Hua smiled, with a relaxed and natural look on his face. He was not surprised by the result and nodded in reply.
Lin Wan stood beside him, acting as his assistant. He held a test notebook in his left hand and a pen in his right hand, carefully recording every test data.
Time passed slowly, and after ten minutes, the entire prototype vehicle running at the highest speed was running normally without any problems.
"That's it, that's it for the appetizers. Let's serve today's big meal and order the prototype vehicle to drive to the loading and unloading point and enter the overload test according to the predetermined plan." Yu Hua gave the order to the dispatcher to end the test and announced that the overload test phase was entered.
.
The standard load test can only be regarded as an appetizer at best, and the overload phase is the highlight.
When the order was given, the dispatcher quickly waved the flag and conveyed the order to the prototype vehicle through semaphores. Soon after receiving the order, Tao Fang drove the prototype vehicle to the loading and unloading point to prepare for loading.
At the same time, Lin Wan, who was responsible for recording the test data, put down the pen with her right hand and wrote the word "passed" repeatedly in the blank area of the marked test results.
Loading and unloading point.
Tao Fang drove the Red Star tractor and stopped steadily next to the electric hoist. The two soldiers quickly got busy. One person controlled the equipment and the other was responsible for connecting the weights. They worked together to lift the weights to the container with the highest efficiency.
piece.
Five dollars.
Ten dollars.
Twenty dollars.
There are more and more 100 kilogram weights, the height of the cargo box is gradually reduced, the fourteen spring steel plates are slightly bent and stressed, and the four high-performance load-carrying tires that use embedded steel wire technology to meet the quasi-steel wire tire standard are slightly deformed.
"Already four and a half tons..." Looking at the increasing weights in the cargo box, Tao Fang, the driver, felt his eyelids twitching wildly and his breathing tense.
Four and a half tons, before, this was a figure that he would never dare to imagine. Even if he had experience driving a Dodge truck, he would not dare to load so many things.
However, the weight is still increasing.
Piece after piece...
Three minutes later, as the last weight was loaded into the cargo box, the first round of overload testing came...
Five tons!
Yes, there is no transition period like two tons or three tons, just five times overload.
"Five tons..." In the observation area, Li Qiang listened to the real-time load capacity data reported in his ears, his breathing was slightly tense, and his palms were a little sweaty. He did not expect that the overload test would be so violent.
Two, three, and four tons are omitted directly, and the starting value is five tons.
God, do you want to be so exaggerated?
Not only Li Qiang was nervous, General Liu and other army representatives in the observation area were all in a state of nervousness, staring intently at the overloaded prototype vehicle for fear of something going wrong.
As for Professor Zhuang among the crowd, his face was natural and did not show any signs of nervousness.
Here, everything was ready for the overload test. Tao Fang, who was the center of attention, raised his sleeve and wiped the sweat from his forehead. He grasped the rocker handle tightly with his right hand, inserted it into the starting port, and started to rotate with all his strength.
"Thud, tug, tug..." A few seconds later, the exclusive sound from the horizontal-bar diesel engine came out again, spreading throughout the entire venue like running water.
Successfully started, board the car!
At this moment, everyone felt as if they were facing a formidable enemy and their spirits were tense.
Tao Fang had a serious look on his face and started working with his hands, shifting into first gear, releasing the clutch, and pressing the accelerator.
The metal chimney emits bursts of black smoke. The high-speed crankshaft pulls the piston through the crank and performs reciprocating motion. The entire single-cylinder diesel engine bursts out with the strongest power. The high-torque transmission system instantly amplifies the power of a mere twelve horses by dozens.
times, and then transmits the power through the large flywheel.
At this moment, this single-cylinder engine is not fighting for itself, it is fighting on behalf of the horizontal-bar diesel engine family!
Half a second later, the Red Star tractor, with a total load capacity of five tons, moved.
The movements were normal, the posture was calm, and there was a majestic aura like a majestic mountain. It no longer had the agility when the car was empty. Under everyone's gaze, the entire prototype car ran steadily while pulling a five-ton weight.
stand up.
"Let's run! Let's run!" After a brief silence in the viewing area, along with an excited cry from an unknown source, all the audience once again gave the warmest applause.
"It can already pull five tons. God, where did Professor Zhuang and Yu Hua come from?" Li Qiang was full of surprise. Compared with the comrades around him, he, who had been in the Soviet Union for a long time, knew very well that the people in front of him were
The gold content of Taihongxing tractors.
The Soviet Union simply did not have such a tractor that could carry five tons with only twelve horses. The important thing is that the tractor in front of you seems to be able to pull more.
After three minutes of acceleration along the circular driveway, the five-ton overloaded prototype finally maintained a speed of 21 kilometers per hour.
"Continue to increase the load!" After Yu Hua obtained a series of actual data on the five-ton overload, he did not hesitate to issue new instructions.
Next, the prototype vehicle continued to increase its load capacity.
Six tons, twenty kilometers per hour.
Seven tons, eighteen kilometers per hour.
Eight tons, sixteen kilometers per hour.
Time gradually passed, and at 8:50 in the evening, as the test data of the nine-ton load capacity came out, the load capacity was only one step away from the double-digit mark.
Nine tons load, twelve kilometers per hour.——
