Replay 07: Opening the Temple of Learning

Chapter 62: You are all-powerful? (Seeking follow-up reading)
Spring is a very common mechanical industrial product.

It can be used in simple light industrial products such as mattresses and ballpoint pens.

It can also be used in heavy industrial products such as automobiles, motorcycles, and even guns and tanks.

The reason why Lu Shan was so confident before was that there were better technical methods to produce high-quality springs.

This is because after he and Poincare studied the principles of spring production equipment in detail, they found the true internal laws from the apparent principles.

This true law is the law of mathematics and physics.

That is, the mathematical laws between the actual properties of the spring and the parameters of the mechanical equipment and the material parameters.

Everything in the universe follows its own rules.

Similarly, the production of mechanical equipment and products also follows rules.

As long as you understand this pattern, you can apply it to other situations and come up with many similar things.

Lu Shan felt that he had figured out the production rules of springs.

Anyway, the time has been spent, and my dad can use this method to improve other spring production equipment in the future.

So Lu Shan planned to write a paper based on the systematic rules he had figured out.

That is, "Research on Optimization Method of Processing Parameters of Multi-Strand Helical Springs".

This is what Lu Shan wrote in the abstract of the paper.

The research on the coupling mechanism of processing parameters of multi-strand helical springs (multi-strand springs for short) on the quality of their finished products is still incomplete, which leads to a low processing qualification rate of multi-strand springs and great difficulty in promotion. Therefore, an experimental method for optimizing the process parameters of multi-strand springs is proposed.

This paper uses the binary method to obtain the twisting pitch that meets the stiffness requirements of the multi-strand spring. The experimental design method is used to design the optimization experiment of multiple process parameters such as the core shaft diameter, spring pitch and wire tension. The optimal multi-strand spring processing parameter group is obtained through the signal-to-noise ratio mean analysis, and the method is verified through the actual production of drill rod reset multi-strand springs. The research results show that the experimental method for optimizing the process parameters of multi-strand springs is feasible, which can reduce the time for obtaining the manufacturing parameters of multi-strand springs, save the cost of multi-strand spring process research, and provide a reference for improving the quality of corresponding equipment.

The multi-strand coil spring here is of course just a general term, and its technical principle is of course also applicable to single-strand springs.

Lu Shan already had a clear idea for the paper in his mind. The first part of the paper was of course the introduction, which briefly introduced the relevant concepts of multi-strand springs and some parameters of the machine equipment.

One of the sentences is: In some specific occasions, due to the constraints of materials, structure and other factors, ordinary single-strand springs cannot meet the design needs. Therefore, multi-strand springs are becoming more and more widely used in civil fields such as automobiles and aircraft.

Next comes the theoretical basis of the calculation and the experiment of the theory.

The calculations include: multi-strand spring stiffness verification, signal-to-noise ratio calculation, signal-to-noise ratio mean analysis, comparative experimental analysis, etc.

The final conclusion is of course to provide the corresponding calculation formulas for the raw materials, equipment, etc. for producing high-quality springs, as well as the coupling mechanism of processing parameters.

There is not a single word of nonsense in the paper written by Lu Shan, it is all solid stuff.

Moreover, the paper is not long. Including the experimental instructions, calculation instructions, calculation formulas, corresponding comparative analysis tables, etc., it is only 20 pages in total.

In order to save time in real life, Lu Shan finished writing the paper in one go at the Singularity Laboratory.

In addition to the paper, Lu Shan also wrote the corresponding operation manual.

In this way, Lu Dehai can follow the instructions and become proficient in any equipment for producing springs.

After completing the thesis.

Lu Shan felt itchy!

Isn't it a waste of talent if you write a paper but don't publish it?
This paper is not an academic paper, but a practical paper, and it is a paper that is only practical in China.

After all, foreign machinery and equipment production technology is far ahead of domestic ones.

Lu Shan's requirements were not high. He only wanted to publish in a third-rate journal. According to the analysis standards of the Xiaguo Academy of Sciences, it would be fine if it could be published in a journal in Zone 3 or even Zone 4. If he could earn ten points, it would be ten points.

No matter how small a mosquito is, it is still meat.

Lu Shan really doesn't have many channels.

He submits his paper to the corresponding journal as an individual, but others may not even read it.

So this kind of thing has to be solved with the help of Chen Qiyi.

It may be more troublesome to publish in journals in Zone 1 and Zone 2.

However, for journals in Zone 3 or 4, Chen Qiyi can just say hello and the review editors of these magazines will probably not throw Lu Shan's paper into the trash.

Lu Shan called Chen Qiyi.

"Dean Chen, I have a small matter to trouble you with."

Chen Qiyi, who has returned home to prepare for the Spring Festival, is drinking tea and walking his bird in the park with some old friends.

He was still very happy after receiving Lu Shan's call.

Students like Lu Shan appear only once in a century.

Lu Shan was willing to communicate with him more, and Chen Qiyi was of course happy to share as well.

Lu Shan said, "Dean Chen, I have a paper on mechanical equipment. Can you recommend a few journals that can be published? Either zone 3 or zone 4 is fine."

Lu Shan's words made Chen Qiyi very confused.

In Chen Qiyi's opinion, Lu Shan has no problem in mathematics and has made great achievements, and can even give guidance to graduate students on their theses.

But unexpectedly, when Lu Shan called, he was not talking about mathematics, but about mechanical equipment.

Chen Qiyi put the mealworms into the bird feeder and said curiously, "Papers related to mechanical equipment? When did you become interested in and research mechanical equipment?"

This kid is all-powerful?
Chen Qiyi felt that this matter was very important and he had to get to the bottom of it.

Lu Shan chuckled and found a perfect excuse.

"It's like this. My dad used to be a technician at the Jiangcheng County Tractor Factory. After coming to Jiangzhou City, he worked odd jobs in a machinery factory. The boss saw that he had decent skills and finally made him a regular employee."

"You also know that it is not easy for technical workers to earn a salary nowadays. If you want to earn more, you have to get a professional title and publish papers."

Chen Qiyi had heard that Lu Shan's father was working, so he believed what Lu Shan said.

"You mean it's OK to publish papers in Zone 3 or Zone 4? They're mainly used for job title evaluation or work needs!"

"Yes, yes, yes! Dean Chen, you see I don't know much about this, can you please help me? I think the paper is of a certain quality, and it shouldn't be a problem to publish it in Zone 4."

In fact, the papers in Zone 4 are basically occupied by engineers who are evaluating their intermediate and junior professional titles. As long as the quality of your paper is not too bad, you can publish it if you pay.

Chen Qiyi said, "It's no problem for this little thing. Just send your paper to my email address and I'll tell the leaders of the School of Mechanical Engineering to give it to you in Zone 3. As long as the quality is barely acceptable, it's fine."
