————————————

Seeing Lao Zhu nodding in agreement, Zhao Guoyang continued to speak: "K is a normal number. Since the straddle motorcycle frame is heavier, this value is higher, and it should be 160-190. As for the bend beam frame, this value should be 130-160."

Hearing this, Lao Zhu nodded. He could barely understand the formula Zhao Guoyang just said.

At least this normal number is not nonsense, but I affirmed that the straddle riding style is larger than the curved beam car.

Zhao Guoyang pointed to a series of data on the paper and then explained: "In the first formula, G represents the curb mass of the motorcycle, g represents acceleration, w represents the peak adhesion coefficient between the tire and the ground, d1 represents the vertical distance between the center of the bearing under the frame riser and the center of the tire, d2 represents the distance between the center of the bearing under the frame riser and the distance between the center of the bearing under the frame riser and the center of the tire. e represents the horizontal distance between the center of the bearing under the frame riser and the center of the tire."

"Then according to this formula, the horizontal reciprocating load F(0) of the frame is easy to calculate."

Zhao Guoyang wrote a series of data, and finally concluded that the horizontal reciprocating load F(0) of the straddle frame produced in the factory was about 800. However, the horizontal reciprocating load F(0) of the C100 frame reached more than 1,000.

Of course, the one-way vertical upward load F(Z) and the one-way vertical downward load F(S) are still larger.

Zhao Guoyang said earnestly: "Old Master Zhu, data will not be lie. You have also seen that although the vertical load of the cross-rider type is larger, the reciprocating load in the horizontal direction is not as large as our new model."

"The main function of the head tube is to decompose the reciprocating load in the horizontal direction, so of course we need to use materials with greater tensile strength and yield strength to manufacture it."

Perhaps worried that Lao Zhu would not believe it, Zhao Guoyang circled the formula on this piece of paper and said with a smile: "Master Zhu, this formula is a load calculation formula that is often used in motorcycle calculations."

"If you don't believe it, you can hold this piece of paper and ask someone to check it out to see if I'm talking nonsense!"

"No need, I, Lao Zhu, believe you!" After hearing this, Lao Zhu didn't even have any doubts.

Although he couldn't quite understand the many formulas written by Zhao Guoyang, the truth was obvious.

Indeed, compared with straddle frames, the center of the lower bearing of the frame riser of the bend beam frame is lower, and the load is subjected to a greater horizontal direction, which is understandable.

Lao Zhu is not easily convinced, but once he is convinced, he will never disobey the evil spirits.

He immediately took the drawings from Zhang Chaoyang and said, "Secretary Zhao, I'm sorry, I was too empirical before. The parts of this frame will be made as you said. We'll start construction now!"

When Zhao Guoyang saw that Lao Zhu was really convinced, he was quite pleased. He then took out a pack of cigarettes and distributed them to Lao Zhu and the workers behind him. He said politely: "Don't be anxious, don't be anxious, everyone smokes a cigarette first. Actually, I'm also reflecting, is there a better way for our technical department to deal with this matter?"

Zhao Guoyang took a sip of cigarette and turned to the workshop director Zhang Fusheng and said, "Director Zhang, if our comrades in the technical department can communicate with your workshop in advance, some problems can be solved easily, and there will be no conflicts when the on-site production is done."

Zhang Fusheng spitted a mouthful of smoke rings and looked at Zhao Guoyang with admiration and said, "Guoyang, you are indeed worthy of being a college student, and what you are saying is reasonable."

"Actually, sometimes the drawings and instructions given by your technical department are all confused in our workshop, but we are just doing things based on experience."

"If it weren't for Lao Zhu's inspection, it would have been a mistake once or twice. When he asked questions today, I was a little confused. After all, Lao Zhu is experienced and he is the technical support of our workshop."

Zhang Fusheng glanced at Zhao Guoyang who was nodding silently and said with a smile: "But Guoyang, you have taught us all a lesson today."

"Although experience can often play a certain role, in the final analysis, everything we do still needs to be based on scientific basis. The formula you just listed really makes everyone feel doubtful, it's amazing!"

Old Zhu next to him nodded and echoed: "Director is right. Section Chief Zhao, you have taught everyone a lesson."

"Chaoyang, Changyuan, you two should learn more with you Section Chief Zhao, and don't always ask questions or not."

When Lao Zhu mentioned himself, Zhang Chaoyang and Chang Yuan looked at me, and I looked at you, and they looked embarrassed.

Zhang Chaoyang coughed and reluctantly explained: "Old Zhu, our section chief is a college student, and his education is much higher than ours. We can't learn his level."

"Hey, there are not so many words. It's like the formula just now. Even if you haven't touched it before, can't you write it down? There will always be times when it is used in the future!" Old Zhu said earnestly.

"Okay, can't we be wrong?" Zhang Chaoyang shook his head helplessly and said, "After I went back, I copied the formula written by our Section Chief Zhao to ensure that I remember it!"

"Well, that's what's right!" Old Zhu nodded with satisfaction, turned to look at Zhao Guoyang and said.

"Secretary Zhao, I think it is necessary to communicate the communication issues you just mentioned. Production and technology have always been inseparable."

"In the past, you technical department people came to the workshop too few times, and everyone had almost no communication, which also caused some estrangement."

"To be honest, you technical personnel are usually a little arrogant. Even if we are Director Zhang, they don't listen very much. I am a straightforward person. Section Chief Xiao Zhao, don't take it to your heart."

After hearing Lao Zhu's constant firecrackers, Zhang Fusheng scratched his head.

Zhao Guoyang patted Zhang Fusheng's arm comfortably and said with a smile: "Director Zhang, Master Zhu, this is indeed our problem. The technical department is originally for production, and your opinions are very important to us. Sometimes, if the technical drawings are wrong, if production can be discovered in time, it can avoid a lot of losses for our factory."

"Yes, yes, this is indeed the truth! Although Lao Zhu has a bad temper, he does a good job in technical control." Zhang Fusheng nodded in approval.

"I remember that last year, Chief Huang from your technical department asked someone to bring in an incorrect drawing. If it weren't for our Lao Zhu's discovery in time, there would be a batch accident. Chaoyang, tell me, is there such a thing?"

Zhang Chaoyang nodded awkwardly when he heard this, and said, "It's true. Section Chief Huang was careless that time and reversed the two dimensions on the drawings..."

"Okay, that's what I mean!" Zhang Fusheng looked at Zhao Guoyang and said.
Chapter completed!
