"Xiao Zhou, do you have any opinion on this issue?" Wang Shuo keenly captured the change in Zhou Jingming's expression, and couldn't help but ask in a low voice.

After all, Zheng Tongya has been his old friend for many years, and Wang Shuo naturally doesn't want him to be affected by this incident.

"Wait a minute, I'm still thinking about it. Zhou Jingming frowned and replied softly.

The car as a whole, all its performance, are closely linked, power, fuel economy, handling stability, smoothness and passability, these indicators, in the design of vehicle parameters, can not independently match any of the parameters, because there are many parameters, is the relationship between one and the other, engineers need to find a most reasonable range, so that these performance to achieve unity.

Take the passability of the car as an example, it is compatible with the smoothness and operational stability of the car, when designing, there is a contradiction, blindly pursuing the passability, the ride of the car will inevitably be affected, and on the contrary, if you prefer other performance, then the passability will also be weakened.

Zhou Jingming remembers that before he was reborn, he often saw such reports on the Internet, saying that the local tyrant drove a Lamborghini and wanted to show off in the countryside, but because the chassis of the car was too low, the car could not drive at all on the dirt road in the countryside.

From the perspective of automobile theory, the reason for this situation is that the gap of the car is insufficient and dragged by the ground, which is called gap failure or jacking failure, which is one of the situations of insufficient passability of the car.

In contrast to jacking failure, there are two manifestations of insufficient passability: contact failure and tail failure.

Since Zhou Jingming said so, Wang Shuo didn't bother anymore, but quietly waited for Zhou Jingming to give his own solution.

"Director Hu, I don't know what I reported about this problem, can you help solve it?" Zheng Tongya, who was standing there like a green pine, asked with a somewhat anxious face.

"Comrade Zheng, are you in a hurry?" Hu Yulou frowned deeply and asked a little ambiguously. In fact, Hu Yulou also knew in his heart that if it wasn't a very urgent situation, the front combat troops would not have let Zheng Tongya rush over in such a hurry, after all, it was only last week that this batch of trucks was transported there.

"Don't hide it, 100,000 urgent! If the passability of the car cannot meet the requirements, it will greatly affect the transportation of personnel and materials of our army, and it is not conducive to the development of our army's operation, so please Director Hu!" Zheng Tongya said that he gave a military salute to Hu Yulou again.

Zhou Jingming took a deep look at the resolute PLA soldier, the comrade's eyes were bloodshot, and his face was also visibly tired.

How can there be any quiet years, but someone is carrying the weight for you!

When Hu Yulou heard this, his brows furrowed even deeper, this matter really can't be dragged on. I saw him around the side of the Dongfeng ironclad off-road vehicle, sometimes checking the wheels, sometimes squatting down to look up at the chassis of the car, as the director of the second automobile technology, no one can know the technical status of this car better than Hu Yulou, because he is one of the main designers of this car.

When this car was designed, the data that passed the sex test were completely destroyed by the domestic military vehicles of the same level, and the outstanding performance in the counterattack against Vietnam made this car famous, but I didn't expect that it would also encounter such a problem.

But no matter how Hu Yulou racked his brains to think about it, he just didn't understand what went wrong.

"Is there a tape measure?" At this time, Zhou Jingming on the side suddenly said loudly.

"And pen and paper!" Zhou Jingming added.

Hu Yulou was stunned for a moment, and then quickly nodded and said, "Yes, yes, I'll have someone bring it over immediately!"

Zhou Jingming is a typical example set up in the ministry, Hu Yulou has also heard of many of his deeds, whether it is the VR6 engine project, or the invention of direct injection technology in the cylinder, all of them were thought up by this young man, looking at his current appearance, maybe he can really solve this matter!

Soon, Hu Yulou's secretary ran over with a tape measure and a pen and paper, and after Zhou Jingming took the things, he didn't say much, he walked directly to the car, began to measure the diameter of the wheel, and the width of the tire, and then quickly made a record while measuring.

Subsequently, Zhou Jingming didn't care about any image, and directly drilled under the car to measure the gap between the middle of the car and the ground and several other related parameters.

Everyone, including Zheng Tongya, looked at Zhou Jingming who was busy with some doubts, wanting to see what Zhou Jingming would do next.

"Director Hu, who is this comrade?" asked Zheng Tongya very curiously. He had been to the Second Automobile many times before, but he had never seen Zhou Jingming.

"This is a comrade from SAIC, named Zhou Jingming, who came here to discuss with me about something. Hu Yulou replied.

Although Hu Yulou was answering Zheng Tongya's question, his eyes kept on Zhou Jingming, Zhou Jingming must have a plan for such a fanfare, otherwise it would not be like this.

Soon, Zhou Jingming got out of the car in dust, and several data were recorded on the paper.

"Director Hu, what is the specific angle of approach of this car?" Zhou Jingming asked without looking up at the dust on his body.

"38 degrees!" Hu Yulou immediately reported the data.

"Where's the corner of departure?" Zhou Jingming continued to ask.

"30 degrees!"

"Minimum turning radius?"

"18 meters!"

"What about the hitch traction coefficient?"

…………

Every time Zhou Jingming asks a parameter, Hu Yulou can give a very sure answer, and he can't be more familiar with the technical state of this car.

These parameters asked by Zhou Jingming, whether it is the approach angle or the traction coefficient, are the main evaluation indicators of the car's passability.

"Is there anything else you want to know?" asked Hu Yulou.

Zhou Jingming shook his head, did not continue to speak, but held a pen in his hand, thinking seriously, and at the same time wrote something on it from time to time, maybe it was too tired to stand and calculate, Zhou Jingming simply lay on the front cover of the car, and in the entire playground, there was only the rustling sound of paper and pen rubbing.

One-page, two-page......

One minute, two minutes......

Everyone was anxiously waiting for Zhou Jingming, and Hu Yulou was even more anxious to move back and forth......

"Huh ......" Finally, when everyone was in no hurry, Zhou Jingming finally took a long breath, then looked at Hu Yulou and said, "I just calculated, the temporary measure is to increase the diameter of the wheel, as for the follow-up permanent measures, maybe the structure of the relevant parts needs to be changed." ”
