All round car designer

Chapter 35 Bench Test

In the dormitory, Jiang Yang was sitting in front of the computer, making a final check on the dimensions of the frame and other parts.

"This place is reduced by 20mm, and the shaft diameter of the hub is increased by 5mm..." Jiang Yang made notes on paper while making revisions on the computer.

The modified parts are put back into the assembly interface of CATIA, and after certain constraints are imposed, they become an assembly entity again.

"Theoretically, this is the final size of the racing car. However, due to the existence of processing and assembly errors, plus some performance adjustments, the final actual size should be adjusted again, but the adjustment will not be too large. Large, all within the calculation range of my size chain."

Nearly an hour later, Jiang Yang turned around, pointed to the complete assembly drawing on the computer and said.

Xueba is Xueba, and his theory is clear and logical, which is much better than Zhou Fei, a half-baked guy.

"Now that the theoretical value has been determined, next, let's explode the technical drawings of the parts that require special processing, such as wheels and brakes, and bring these drawings to Mr. Xu tomorrow, and ask him to find a manufacturer for processing."

Zhou Fei glanced at the [-]D model, then grinned.

Judging from the appearance of the car, the car they designed is not much different from the car of the Geeze team. After all, the cars used in formula races are roughly the same in appearance.

What's really different about a race car is what's at its core!

Including a complete set of power system, frame and the materials used for these parts, and the difference in these cores is directly reflected in the power, handling and driving comfort of the car.

Although it has not yet entered the trial stage, Zhou Fei believes that the racing car he designed will never disappoint anyone!

"Brother Fei, don't we really need to do aerodynamic experiments with this racing car?"

Although the theoretical part of the design has been completed, Jiang Yang still feels uneasy. After all, the theory is just a theory, and no one dares to guarantee it before it has been tested in practice.

But Zhou Fei shook his head with a smile, "Don't worry, the aerodynamic characteristics of this car are definitely better than that of the Jisu team, or any other team. There is no need to do more experiments."

Zhou Fei naturally knows what the aerodynamic experiment that Jiang Yang is talking about is the wind tunnel test. Jisu Racing Team will do several times for its own car every season, but Mercedes-Benz Racing Team does not have this requirement.

Besides, for the body shape of this car, Zhou Fei borrowed from the car design of the previous Ferrari team. Compared with the Ferrari team, which has brought the car design to the extreme, the wind tunnel test of the Jisu team seems very tasteless.

"Okay, then let's get out the technical drawings of these parts today." Jiang Yang finally chose to believe Zhou Fei.

Just like Jiang Yang thought at the beginning that the two of them alone could not complete the design of a racing car, but the reality is that after he returned to school, Zhou Fei had already completed most of the design work such as engine modification .

If it wasn't for Zhou Fei not being good at theoretical calculations, Jiang Yang felt that Zhou Fei could complete all the work by himself without the need for himself!
And all this added up, less than a month!
Although it is not clear how the design progress of the Jisu team is, Jiang Yang believes that the progress of the other party is definitely not as good as that of the Mercedes-Benz team!
With the current work foundation, Jiang Yang now begins to really believe that Zhou Fei's words about winning this year's championship are not joking...

Jiang Yang felt that there were really more and more secrets about Zhou Fei.

At around [-]:[-] in the afternoon, the two of them were still fighting in front of the computer. With the efforts of the two of them, drawings of parts and components had been born one after another. The materials and related technical requirements for the parts and components were marked in detail on the drawings. You only need to produce directly according to the drawings.

After finishing drawing another part diagram, Zhou Fei stood up from the chair, ready to exercise his muscles and bones. Not long after he got the mobile phone, he received a call from Xu Nan.

"Zhou Fei, if you have time, come to the laboratory. The EFI system has been prepared and sent to me, and the bench test can be carried out immediately."

Xu Nan's voice came from the other end of the phone.

"So soon?" Zhou Fei was overjoyed, "Okay Teacher Xu, we'll be there soon!"

The EFI system can be said to be the most important part of this racing car. Of course Zhou Fei wants to witness for himself how this system can improve the performance of the engine.

"Stop drawing, come with me to Mr. Xu's place. Mr. Xu has already got the electronic injection system I showed you earlier, and we are going to conduct a bench test soon."

After Zhou Fei hung up the phone, he hurriedly said to Jiang Yang.

On the first day Jiang Yang came back, Zhou Fei had already shown him all the information of the EFI system. To be honest, Jiang Yang thought it was a very genius idea!

Although he hasn't fully understood the working principle of the EFI system for the time being, let alone how Zhou Fei figured out how to use this method to realize fuel injection, Jiang Yang is very aware of the value of this system.

Because he has collected all the papers that can be published on the Internet, although many of them are about fuel injection, and many foreign engineers have touched the threshold of EFI, but like Zhou Fei, he has completely completed the entire design of the EFI system Work, and summarize all the theoretical content, so far there is no one!
In other words, Zhou Fei is likely to become the one who created the history of fuel injection!

What an achievement this is, Jiang Yang can't even imagine, it must be much more difficult than winning the national award anyway!

"Okay, I'll go with you now." Jiang Yang quickly put down the work at hand, and followed Zhou Fei towards the laboratory.

The two soon saw the newly unpacked EFI system in Xu Nan's laboratory. Compared with the purely mechanical design of the carburetor, the structure of the EFI system was greatly simplified, especially the integration of the ECU. The design makes the whole system look more intensive.

Zhou Fei squatted down, held it in his hand carefully and looked at it, it was similar to the EFI system he encountered in the car factory in his previous life.

"Mr. Xu, how is the structural modification of that CRT single-cylinder machine?" Zhou Fei turned his head and asked.

"It has been modified according to your requirements. If necessary, the bench test can be carried out now." Xu Nan also looked eager to try. It has been a long time since he had such a great interest in an experiment.

Zhou Fei nodded with a smile, "Okay, then let's start, please trouble Teacher Xu."

Under the leadership of Xu Nan, Zhou Fei and Jiang Yang soon came to the engine laboratory. On the test bench, two CRT single-cylinder engines have been placed there. On the CRT engine, the bench test can be carried out immediately.
