Thanks to the good names that have made people register yy, Qing Wu Feiyang 11, the emotional single-minded playboy, the big soldier 1113, the flower blooms far away, the left zheng, the little kitten catches a big fish, feng951, , the advent of the ice less, the end of the world 001, laughing a sword, Huanhuan Xiaodao, stupid book 6, classic string ball, the demon is ready to die and other good friends of the reward support, I will definitely work harder, next week the old rules, continue to walk up three chapters a day, I hope you like to support a lot, if you are free, you can reply to the post, I watch it every day, and I can also enter the genuine group and communicate together, let's watch how Zhao Guoyang walks out of a road of industrial rejuvenation Zhao Guoyang saw that Lao Zhu nodded in approval, and continued to speak: "K is a normal number, and the straddle motorcycle frame is heavier due to its own weight, so this value is higher, and it should be 160190."
Hearing this, Lao Zhu nodded.
The formula that Zhao Guoyang just said, he can barely understand.
At least this repair normal number, people are not talking nonsense, but affirm that the straddle type is bigger 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 weight of the motorcycle, g represents the acceleration, w represents the peak adhesion coefficient between the tire and the ground, d1 represents the vertical distance from the bearing center under the frame riser to the tire center, and d2 represents the distance from the bearing center under the frame riser to the ground. e represents the horizontal distance from the center of the bearing under the riser of the frame to the center of the tire. ” "Then according to this formula, the horizontal reciprocating load of the frame f0 is very easy to calculate."
Zhao Guoyang wrote a series of data, and finally came to the conclusion that the horizontal reciprocating load f0 of the straddle frame produced in the factory before was about 800.
However, the horizontal reciprocating load F0 of the C100 frame has reached more than 1000.
Of course, the one-way vertically up load fz and the one-way vertically down load fs are still larger for the straddle frame.
Zhao Guoyang said earnestly: "Master Zhu, data will not deceive people.
As you can see, although the vertical load of the straddle is greater, the reciprocating load in the horizontal direction is not as large as that of our new model. ” "The main function of the head tube is to decompose the reciprocating load in the horizontal direction, so of course, we have to use materials with greater tensile strength and yield strength to manufacture this piece."
Perhaps worried that Lao Zhu would not believe it, Zhao Guoyang drew a circle of the formula on this piece of paper, and said with a smile: "Master Zhu, this formula is a load calculation formula often used in motorcycle calculations. ” "If you don't believe it, you can take this piece of paper and ask someone to check it out to see if I'm talking nonsense."
"No need, my old Zhu believes you" Hearing this, where would Lao Zhu still have questions.
Although he can't understand the large number of formulas written by Zhao Guoyang, the truth is obvious.
Indeed, it's understandable that a curved beam frame has a lower bearing center under the frame riser and is subjected to more load horizontally than a straddle frame.
Lao Zhu is not easy to convince people, but once he is convinced, he will never disobey again.
He immediately took the drawings in Zhang Chaoyang's hand and said: "Section Chief Zhao, I'm sorry, I was too empirical before, the parts of this frame are made, just do what you say, and we will start work."
Zhao Guoyang was quite relieved to see that Lao Zhu was really convinced, and then took out a pack of cigarettes, scattered them to Lao Zhu and the workers behind him, and said politely: "Don't worry, don't worry, the big guy will smoke a cigarette first."
In fact, I'm also reflecting on whether our technical department has a better way to deal with this matter."
Zhao Guoyang took a puff of cigarette, turned his head to Zhang Fusheng, the director of the workshop, and said: "Director Zhang, if the comrades of our technical department can communicate with your workshop in advance, some problems can be easily solved, and there is no need to have conflicts when there is on-site production." ” Zhang Fusheng spat out the smoke ring, looked at Zhao Guoyang with admiration and said: "Guoyang, you really deserve to be a college student, what you said is reasonable." ” "In fact, sometimes the drawings and instructions given by your technical department are all in the clouds in our workshop, and we are just doing things based on experience."
"If it weren't for Lao Zhu's check, the mistake would definitely not have been once or twice.
When he raised questions today, I also had some doubts in my heart, after all, Lao Zhu is experienced, and he is the technical support of our workshop. ” Zhang Fusheng glanced at Zhao Guoyang, who nodded silently, and said with a smile: "However, Guoyang, you can be regarded as teaching all of us a lesson today." ” "Although experience can indeed play a certain role in many cases, but in the final analysis, everything we do still has to be based on science, and the formula you listed just now really relieved everyone's doubts, amazing" Lao Zhu next to him listened to Zhang Fusheng's words, so he nodded and agreed: "What the director said is right, Section Chief Zhao, you can teach the big guy a lesson." ” "Chaoyang, Chang Yuan, you two have to learn more from your Section Chief Zhao, don't always ask questions and don't know anything."
Seeing that Lao Zhu mentioned himself, Zhang Chaoyang and Chang Yuan, you look at me, I look at you, they are all embarrassed.
Zhang Chaoyang coughed and reluctantly explained: "Lao Zhu, our section chief is a college student, and his education is much higher than ours."
We can't learn from his level. ” "Well, that's not all.
It's like the formula just now, even if you haven't touched it before, can't you write it down and use it in the future," Lao Zhu said earnestly.
"Yes, can't we be wrong" Zhang Chaoyang shook his head helplessly and said, "After Chang Yuan and I go back, I will copy down the formula written by our Section Chief Zhao and ensure that I remember it firmly."
"Well, this is like words" Lao Zhu nodded with satisfaction, turned his head to look at Zhao Guoyang and said.
"Section Chief Zhao, I think it's necessary to talk about the communication problem you just mentioned.
Production and technology have always been inseparable. ” "In the past, the number of people from your technical department came down to the workshop was too small, and there was almost no communication between them, which also caused some estrangement."
"To be honest, the people in your technical department are usually a little arrogant, even if it is our Director Zhang's words, they don't listen to it, I speak straight, Xiao Zhao, don't take it to heart."
Listening to Lao Zhu's non-stop firing of guns, Zhang Fusheng scratched his head for a while.
Zhao Guoyang patted Zhang Fusheng's arm comfortingly, and said with a smile: "Director Zhang, Master Zhu, this is indeed our problem.
The technical department is meant to serve production, and your opinion is important to us.
Sometimes, the technical drawings are wrong, and if the production can be found in time, it can avoid a lot of losses for our factory. ” "Yes, yes, yes, this is indeed the truth, although Lao Zhu is not very good-tempered, but in terms of technical control, he really does a good job."
Zhang Fusheng nodded approvingly.
"I remember that last year, the head of your technical department, Huang, asked people to bring a wrong drawing, if our Lao Zhu hadn't found out in time, there would have been a batch of accidents.
Chaoyang, tell me, is there such a thing?"
Zhang Chaoyang nodded awkwardly when he heard this: "Yes, that time, Section Chief Huang was also careless and marked the two dimensions on the drawing in reverse."
"Okay, that's what I mean," Zhang Fusheng looked at Zhao Guoyang and said.
"Guoyang, I agree with the point you just mentioned, since the technical department is for production, then the communication between us should be strengthened
