Looking at Zhao Guoyang's casual design, Hua Guosheng was completely convinced.

He sighed and said, "Guoyang, your design level is really amazing, I am sighing to myself, even if it is Xiao Huang, I can't catch up with you." ”

"Our Hongda Machinery Factory is up and down, I'm afraid that only Director Wang can compare with you......"

"You're talking about Section Chief Huang Xiaohua, right?" Zhao Guoyang's heart moved, and he asked.

Xu Dongfeng on the side was shocked when he heard this: "Hey, Guoyang, how do you know Section Chief Huang, I don't seem to have told you!"

Zhao Guoyang smiled and didn't answer his question.

Hua Guosheng glared at Xu Dongfeng with reprimanding eyes, turned his head to Zhao Guoyang and said: "Xiao Huang has some ability, but he is too arrogant and not easy to get along with. Unlike Guoyang, you are both strong in ability and have no shelf......"

Perhaps because he felt that he was a little provocative when he said this, Hua Guosheng hurriedly coughed and said: "That, Guoyang, I will change the tooling diagram according to your ideas, and strive to change it today!"

"It's okay, there's no hurry. On the shop floor, the parts before were not so fast. These pictures you have in hand, you can give them tomorrow. Zhao Guoyang comforted.

Hua Guosheng and Xu Dongfeng went to change the drawings, and Zhao Guoyang saw that there was nothing wrong with the technical department, so he decided to go to the workshop to take a look at the production progress of other parts.

As soon as he walked into the second production workshop, Zhao Guoyang heard the sound of an argument.

"I said Lao Zhu, why can't you listen to people's persuasion. The tube at the front of this car, we have technically determined that we need to use No. 20 steel, you just follow it, why do you have to use Q235 if you don't have a dead brain?"

The person who spoke was a man named Zhang Chaoyang from the technical department, although he was not very old, only twenty-seven or eighteen. But he has been in the factory for ten years, and he can be regarded as an old man in the technical department.

Zhang Chaoyang usually doesn't like to talk, and he belongs to the type of person who will do whatever the leader arranges.

Although this kind of person is not strong, he can perform the tasks assigned by the leader to the letter.

Many times, it is still very effective, Zhao Guoyang arranged for him and another technician Chang Yuan to come to the workshop to guide production, just to value him for this good.

After Zhang Chaoyang finished speaking, he snorted: "Hmph, it's not that I haven't produced motorcycle frames before, it's bigger than your curved beam frame." ”

"But even with the big frame before, the material used for the front pipe is only Q235. Why is it that now that the frame has shrunk, the materials have to be used better?"

"You people in the technical department know that you have a slap in the head and make decisions randomly. No. 20 steel is much more expensive than Q235, isn't it a waste to be able to toss around like this?" the voice continued.

Although Zhang Chaoyang knew that he had to carry out production according to the requirements of the drawings, it would be difficult for him to say why.

At this time, listening to this man's rebuttal, he was a little speechless.

Seeing that the other party couldn't answer his own question, this man named Lao Zhu came to the spirit: "Hmph, what's the matter, can't you answer, right? If you want me to say, this head tube, just use Q235, absolutely no problem......

Hearing this, Zhao Guoyang couldn't help but step forward and said: "Old Master Zhu, the frame we tried to produce this time is a new model, and the original straddle frame is two concepts. The size of the frame does not mean that it needs to be made of stronger materials. ”

"Hey, Guoyang, are you here?" As soon as he saw Zhao Guoyang, Zhang Fusheng, the workshop director who had been playing a round next to him, hurriedly came over to say hello.

Zhao Guoyang and Zhang Fusheng nodded in acknowledgment, and then put their eyes back on Lao Zhu.

This old Zhu is forty or fifty years old this year, tall and thin, with some white hair, and looks older than his actual age.

He is an old technician in the workshop, and he is the pillar of the workshop because of the speed and precision of making parts.

This person is notoriously stubborn in the factory, and he has always recognized reason and people.

What he decided, even if it was the factory director Mu Aijun, it was difficult for him to change his mind.

Seeing Zhao Guoyang coming, Lao Zhu's eyelids lifted slightly, and he let out a cold snort from his nose. Obviously, he didn't have a good impression of the newly appointed technical chief.

Zhao Guoyang walked to Lao Zhu's side disapprovingly, and explained seriously: "Master Zhu, when making parts, of course, you can question the accuracy of our technical drawings, but after our technicians confirm the correctness of the drawings, you should implement them to the letter." ”

"After all, whether it is manufacturing or technical quality, everyone has to perform their duties and manage their own stalls. Otherwise, you'll just get into chaos. ”

"Then you have to be right! Just say this material selection, I don't think it's reasonable!" Lao Zhu heard this, and his voice rose.

After Lao Zhu finished speaking, a few workers behind him nodded and agreed: "Yes, our Lao Zhu is an old technician, and his experience must be much richer than these yellow-haired boys in the technical department, listen to him!"

Zhao Guoyang was not disturbed by the surrounding voices, he said calmly: "Okay, since Master Zhu, you have to fight for understanding, then I will explain it to you." ”

"If I can explain it to you, I hope that in the production process in the future, you will not be rash and complete the work at hand according to the requirements!"

"Okay, as long as you can convince me, I'll listen to you kid in the future!" Lao Zhu said with a temper.

Zhao Guoyang nodded, took out a pen and notebook, and began to draw and explain at the same time.

"The technical conditions of the two-wheeled motorcycle frame, Master Zhu, you should understand. Next, let's check the strength of our new frame. ”

Zhao Guoyang drew a diagram on which it was written that F(0) was loaded horizontally, F(Z) was loaded vertically upwards in the center of the rear wheel, and F(S) was loaded vertically downward for the rear seat members.

After listing these three values, Zhao Guoyang listed the stress distribution of the frame one by one, and pointed out the possible stress concentration parts one by one.

Zhao Guoyang pointed to a series of values that had been listed, and said to Lao Zhu: "Master Zhu, you must have seen it, the frame of our curved beam car has a different bearing distribution than the original straddle frame. With the overall center of gravity skewed forward, the front of our frame is more susceptible to yield failure. ”

Zhao Guoyang listed a formula and said: "According to the load calculation formula, the horizontal reciprocating load F(0) should be equal to ...... The vertical impact force F (Z) on the rear wheel of the frame should be equal to ...... The vertical downward load F(S) on the rear seat of the frame should be equal to ...... You should understand this Master Zhu, right?"

Lao Zhu looked blankly at Zhao Guoyang listing one formula after another, and nodded subconsciously.

(Note: Horizontal reciprocating load F(0)=[(G+K)g?w?d2-(G+K)g?e]/d1;

The vertical impact force of the road surface on the rear wheel of the frame F(Z)=K(Z)? F（0）；

What is the vertically downward load F(S)=K(Z) on the rear seat of the frame? F（0），）
