The Military-industrial Scientific Research System of the Academic Master Chapter 533

Chapter 533 Madam, you don't want to either…

 “Geological question?”

 This is completely a blind spot in Chang Haonan's knowledge.

 Although all engineering problems can ultimately return to physical problems and then be reduced to mathematical problems.

  But this does not mean that mathematicians can solve all engineering problems in one step.

Even a master like Chang Haonan, who is rich in theoretical knowledge and engineering experience, must first learn basic knowledge when faced with problems he does not understand.

  Or let people analyze the essence of the problem.

 So he thought for a moment and asked:

“Can you be more specific? What type of geological problem is it?”

 “At least I have to be clear about the research object.”

However, the key point is not difficult to get.

Zhu Lan said as he fumbled around in his jacket pocket for a while and took out a small notebook.

 “It cannot be said that it is directly feasible.”

Of course, having said that, you still have to be sure, otherwise it will be like jumping to the top.

"Wait a moment…"

"The research project is...'Vibration response and cumulative permanent deformation of permafrost sites under the load of heavy-duty trains'. The research objects include various undesirable frozen soil phenomena including instability of the water and heat balance conditions of permafrost, changes in the upper limit of frozen soil, etc." The high temperature and extremely unstable permafrost area..."

Reasonable.

Chang Haonan lowered his head and organized his words:

Hearing Chang Haonan's judgment, Zhu Lan's eyes lit up:

 “In other words... it should be feasible?”

 Permafrost, train.

Zhu Lan shook his head:

“This is what my old Lin told me last night when he called me. Because it was an outside call, I didn't mention anything in detail.”

 At this point, Chang Haonan felt that these proper nouns might be a bit unfamiliar, so he changed the subject and asked:

Chang Haonan is nodding his head when he hears the name of this kind of project. It is impossible for Zhu Lan, who is not a professional, to remember it without a notebook.

 “Then let's take it as such for now.”

Chang Haonan already had an estimate in his mind, and he just asked casually. No matter how Zhu Lan answered, he would definitely continue:

“From a theoretical perspective, this problem is probably a composite problem of the temperature field, the stress field inside the frozen soil layer, and the pressure field of external dynamic loads.”

 This is, after all, Lin Guofan's problem, not her professional direction.

 The two keywords put together may not mean anything to people of this era, but for Chang Haonan who has returned from rebirth, it is not difficult to guess where this project is aimed.

“There are no obstacles at the solution level of the core set of partial differential equations, but at the operational level, if a railway is really thousands of kilometers long, even if only part of the permafrost layer is studied, there will be at least a research scope of hundreds of kilometers. Then it is impossible to solve it as a closed domain problem like a general problem.”

“Because these three fields are basically completely independent, the numerical solution of the strongly nonlinear partial differential equations will eventually be implemented, which is exactly what the TORCMultiphysics software is good at, although the calculation process will be more troublesome.”

“Are you planning to build a railway in XZ?”

"Whether it is the finite element method or the finite volume method that is commonly used at present, if you calculate an open domain problem, you must impose truncation boundary conditions. You can consider constructing an interpolation shape function in the local coordinate system, such as Bettess element and Astley element, or directly in Construct interpolation shape functions in the global coordinate system, such as Burnett elements..."

 “Do you need me to write these functions for you?”

 But Zhu Lan shook his head:

“No need, I study surface physics. I have some understanding of what you mentioned. It should be regarded as the infinite element method...”

 “Surface physics…”

Hearing this, Chang Haonan suddenly became energetic:

“Professor Zhu, our company is currently studying the dynamic model of microscopic particles on the surface of metal materials during the grinding process. I wonder if you are interested in participating?”

 Originally, Chang Haonan should have finished talking about the current matter before starting the next topic. However, high-precision abrasive belt grinding will have a great impact on the production efficiency and yield rate of turbofan 10 after it enters mass production in the future. It is one of the core technologies in the third-generation aviation production process.

After all, Chang Haonan himself is not an expert in this field. If he really has to learn it all by himself, it will take some time.

 The most lacking thing in the Turbofan 10 project is time.

Even if the finalization cannot be completed, Chang Haonan still hopes to advance the engine to a state of sufficiently high stability before October 1999.

 Let third-generation fighter jets equipped with domestic engines, even prototypes, participate in the military parade!

Now Zhu Lan's level is definitely high enough and reliable enough. If he can be brought over to lead the project, it will not only advance the research progress, but also be equivalent to finding a teacher for Chang Haonan himself.

No matter how you look at it, you are killing two birds with one stone.

 So I asked immediately.

And this question that turned against guests directly stunned Zhu Lan.

Chang Haonan saw that the other party was worried about the distance between Jincheng and Beijing, so he continued:

"As for the salary issue, you can rest assured that all your expenses in Beijing and the round-trip air tickets from Jincheng to Beijing will be taken care of by us, and we can also give you an additional subsidy based on the basic salary standard of a senior researcher in our group. "

Torch Group is a state-owned enterprise, and the company's money is not Chang Haonan's own money anyway. In addition, there are only a small number of people in the company, so he basically doesn't hesitate at all in offering benefits.

 In this era, the treatment of scientific researchers is generally relatively average.

Especially for research institutions in relatively remote locations like Jincheng University.

Even if Lin Guofan and Zhu Lan are both full senior professors, their lives can only be described as average.

 Facts have proven that adding money is indeed effective.

"I have to discuss this matter with our Lao Lin, but...it shouldn't be a big problem."

Zhu Lan thought for a moment, and although he did not give a direct answer, his tone and expression were basically stable.

“That's good, our group is in urgent need of reliable fresh blood, and we really need talents like Professor Zhu to join us.”

Chang Haonan's on-site poaching not only made Zhu Lan a little confused, but also almost confused the other people at the same table.

However, colleges and universities do not restrict faculty members from taking part-time jobs outside the school, so speaking of it, there is no problem.

 After a small interlude, Zhu Lan and Chang Haonan remembered the topic they had just talked about halfway.

“By the way, the infinite element method I just mentioned...”

Zhu Lan picked up the pen again, preparing to record what Chang Haonan said next.

 But the latter waved his hand directly:

"Since you understand the idea of ​​the infinite element method, there is nothing more to say. We cannot immediately upgrade to a new version for this less commonly used method, but we can develop an external toolkit for the infinite element method through the reserved interface. ”

“Just think of it as part of the cooperation with Professor Zhu to join our research project.”

Chang Haonan said this, obviously continuing to increase the requirements just now——

Ms. Zhu, you don't want your husband's research project to be without useful tools, right?

 Ahem…

Zhu Lan, who was opposite, had no objection to this. After all, apart from the need for a long business trip, she would at least not suffer any loss.

“Then on behalf of my husband, I would like to thank Mr. Chang in advance for his help.”

Zhu Lan said as he put the pen and notebook into his pocket.

 The dinner was almost about to begin. She wanted to say goodbye and leave, but something suddenly occurred to her:

“By the way, Mr. Chang, what is the name of your project? This needs to be reported to our school.”

“Study on the microscopic mechanism of the material surface removed during abrasive belt grinding.”
