As a senior technician from a bearing company, Zhang Xu can naturally realize the weight of this design document in his hand.

Designing parts and components according to process requirements is the basic skill of mechanical design.

Every year, the group assesses the ability level of technical personnel, and there will be questions of similar nature.

Of course, considering the time limit for answering the questions, the difficulty is definitely incomparable.

In fact, if he had led a design team, it would have been possible to do it in a few months.

But what is the process in between......

That's a lot of trial and error, iteration, and optimization.

However, there is no such part of the design document in front of me, but it is a step-by-step process, which seems to set the parameters at the beginning, and then logically calculates to the end.

And guess what?

Hey, I really got him right!

And it's a perfect fit.

If someone hands in this kind of answer in the group's ability level assessment, there is a high probability that Zhang Xu will directly judge a cheat.

In this case, it is either a burst of luck and you have chosen the correct answer among the infinite possibilities with your eyes closed.

It is not enough for the ancestral tomb to emit green smoke, it has to be burned by the ancestral grave.

Either you know the answer in advance, and the steps are just written casually.

In fact, even if it is cheating, few people dare to be so blatant, and it is more or less symbolic to count several rounds.

However, the person who took out this thing was Chang Haonan after all.

People have already made a name for themselves in their own disciplines, and there is no need to call the three of them over to play with them.

Zhang Xu raised his head and glanced at the other two peers next to him and opposite.

From their expressions, Zhang Xu knew that everyone's thoughts should be the same now.

I was curious, but I didn't know how to open my mouth for a while.

In the end, it was Zheng Chaoqun, the technical director from Complex Axis, who broke the silence first.

Fuzhou Bearing is the big brother of Huaxia bearing industry, and Chang Haonan has barely had dealings - the 16 sets of bearings used in the previous experiments were bought from them.

"Mr. Chang, although from the results, there should be no problem, but the design method above is really ...... with us Even if it doesn't match the habits of foreign companies......"

"That's right."

Chang Haonan said something a little awkward.

Immediately afterwards, after the three of them were still a little stunned, they asked rhetorically:

"You should have known about the TORCH Multiphysics software launched by our company, right? I remember the names of the three of you in the trial list. ”

The first to react was Zhang Xu:

"Of course, our group has recently been manufacturing a large-diameter tapered roller bearing for Shengjing Heavy Machinery Group, which is used in super-large water turbines, and this software was used for structural analysis of the entire equipment at that time, although it was a little unaccustomed to it when it first started, and many operations need to be completed with command statements, but the effect is really good."

Obviously, although it hasn't been a long time since the beta was released, TORCH Multiphysics is a revolutionary analysis tool that is already being used in many industries.

It's just that everyone's current imagination is still a little lacking, or they are still in the process of learning and adapting to new tools, and it is not yet time to dig deep into the potential.

They are mainly used in the field of fluid mechanics or structural mechanics analysis.

"Have you ever thought that the functions of TORCH Multiphysics can also be applied to the field of mechanical design? For example, a dynamic analysis of the operating state of a bearing? ”

Chang Haonan's words can be described as a sentence that woke up the dreamer.

"Hiss......"

"What Mr. Chang means is that we can also ...... in this way"

Representative Luo Zhou, who had not spoken just now, asked tentatively.

However, the beautiful dream was soon broken by Chang Haonan:

"Now, I can design this way, but I shouldn't be able to."

"Uh......"

"This ......"

Zhang Xu and Zheng Chaoqun scratched their heads a little embarrassed.

However, they know their own business, and the R&D personnel of these companies actually do not have a deep theoretical foundation, and it is indeed difficult to do this kind of thing in dynamic analysis.

"TORCH Multiphysics comes with plenty of custom interfaces, so theoretically, as long as I give you an accurate dynamical model, you can actually program it to get the corresponding dynamics."

Chang Haonan, who realized that he seemed to have hit the other party's self-confidence a little, hurriedly explained:

"But this requires a high level of user input and output of parameters, and if it goes wrong, it is very easy to cause accidental damage to the source program, and in the worst case, we may even need to send an engineer to do the operation and maintenance for you."

"But."

Speaking of this, Chang Haonan gently tapped on the table:

"I hope to isolate the entire dynamic analysis and calculation process step by step, and encapsulate the core modeling and solving process into the background processing, so as to form a relatively independent tool module, and the professional level of users can be greatly reduced."

Zhang Xu and the other three suddenly showed expressions of surprise.

If the bearing development work can be as easy as the design document in their hands now, then many problems can be solved.

However, Chang Haonan changed the conversation again:

"Of course, this requires a long process, especially a lot of actual data to optimize the different bearing types and operating conditions."

Now, all three people understand:

"So, there's always a hope that we can take advantage of the size and provide this data?"

Zheng Chaoqun asked.

"Yes, but that's not all."

Chang Haonan nodded:

"To make a good bearing, it is not enough to have excellent structural design, material handling, processing technology and even user service, brand building these aspects have to keep up, after all, I am not from the machinery industry, and there are many other projects, it is impossible to put all the energy into these communication and liaison affairs."

"For example, the bearing you just saw, it needs a better bearing steel than the M50 to produce the performance I need."

"Better than the M50, that's the M50NiL......"

The topic finally entered the category that Zhang Xu was more familiar with:

"At present, the domestic special steel for bearings is better, basically Xingcheng Special Steel, Northeast Special Steel and several others, abroad, with us more cooperation is mainly Japan's Tsubaki Nakajima and Datong Steel ......"

"Wait......"

Chang Haonan raised his hand and interrupted him:

"I have a ...... field of application for this bearing. Special, do not consider the import of steel from abroad. ”

"Moreover, even if the steel is imported from abroad, it still does not meet my requirements, and I have to develop higher performance bearing steel."

"Better than the M50NiL?"

Zhang Xu was obviously shocked by this statement:

"M50NiL is already a new steel that SKF has only developed over the years, and now we have not yet conquered the surface treatment technology from M50 to M50NiL in China, but at least there is a general direction, if it is higher than this requirement......"

He hesitated:

"I'm afraid it's going to be hard to come up with in a short period of time."

"Is this...... It doesn't matter. ”

Chang Haonan leaned back in his chair, looking light and breezy:

"You just need to report my needs to the upstream industry, although I don't have much research on metal materials, but in carburizing, nitriding, and guide surface wear, I can still give some qualitative judgments."
