Although Chang Haonan said that it was a brick thrower, Lin Jingtang has been immersed in process numerical calculation for many years after all, and basically belongs to the type of one-point understanding.

Even from the theoretical content of the current drawing board, this seemingly unremarkable new algorithm can greatly reduce the amount of computation in the process of solving the velocity field, which happens to be a relatively time-consuming part of the whole calculation process.

It's a pity that the 112 factory has not sent the specific process parameters over, so the more specific calculation steps are not yet available, and we can only test the universality of several classical volume incompressibility conditions under this problem from the perspective of theoretical model research.

"In addition, Mr. Chang, before the equipment is officially energized and started, we need to test the working status of the hydraulic synchronous deviation correction system separately......"

"The fatigue analysis and reliability testing system that we are responsible for is currently performing open-loop testing ......"

"Stroke Sensing Measurement System for Main Working Hydraulic Cylinders......"

This is the complete opposite of what has since happened.

However, such a super-large equipment like a die forging press, and the surrounding area is a whole new factory in Jiangzhong, the level of power consumption after working is quite terrifying, relying on its own emergency diesel generator is a drop in the bucket, so it must be guaranteed by the local power supply.

Many high-end residences will even have their own diesel engines.

"It's a pity...... Shen Lao didn't see this day. ”

"In view of the occasional lack of energy supply, we took this aspect into account when we first designed, and the safety locking system is in power-on release mode, so we don't have to worry too much."

The others replied in unison.

After a long while, he nodded:

"Okay."

After a few more laps in the workshop, Chang Haonan directly performed a poor dagger:

"I remember, how many of your PhD students who participated in the numerical calculation process of our project were any of them graduated this year?"

After the meeting, Chang Haonan found Yan Yongnian who was routinely inspecting the workshop in the factory.

Chang Haonan raised his head and shifted his gaze from the notebook in front of him to several responsible personnel on both sides of the conference table:

At that time, it was at the most critical stage of the transformation of equipment from drawings to physical objects, so Yan Yongnian, who lacked skills, didn't even make it to attend the other party's funeral.

"Shhh...... If you don't say it, I'm almost forgetting that you haven't graduated yet......"

Chang Haonan also made a special trip to visit the die forging press before the project.

Now Yan Yongnian understood.

“……”

Yan Yongnian turned his head to look at Chang Haonan suddenly, his eyes trembling.

"There are two graduates this year."

"Nope!"

For Chang Haonan, the die forging press is only one of the two large-scale projects at hand at the same time, but for the latter, it is a career that has been fighting for most of his life and almost missed, and it is not an exaggeration to say that he has worked hard all his life, so in terms of the degree of attention, it is higher than Chang Haonan, the chief designer.

In May 1998, Shen Hong died at the age of 92.

"Professor Yan."

"In this way, most of the work items in the cold car state have been completed, and only one synchronous deviation correction system needs to be performed separately for open-loop testing."

Yan Yongnian pushed the brim of his helmet with the antenna of the walkie-talkie in his hand, and said to Chang Haonan, who had just walked up next to him:

Yan Yongnian replied almost without thinking, obviously not realizing the seriousness of the problem:

"Why do you suddenly ask this?"

At the turn of the century, if the power grid is at risk of overload, it will generally choose to prioritize industrial power consumption.

"Then that's all for today, adjournment!"

The two stood on the visual inspection table on the second floor of the workshop, watching the workers not far away climb up and down on the pattern frame, installing some of the last auxiliary equipment in place, as well as decorations that did not play their actual function.

For example, "Jiangcheng Heavy Machinery" has four huge Chinese characters.

And Academician Shen Hong was the person in charge of the project at that time, and he was also Yan Yongnian's teacher.

"The last unplanned power outage here was in February this year, and before the Chinese New Year, the power supply line from the substation was crushed by ice, and it took about 30 hours to restore it."

……

For the super-heavy die forging press, which is a treasure that there are only a few units in the world combined, not to mention just writing down the production enterprise, Yan Yongnian even proposed whether to give it a name similar to a warship.

Yan Yongnian has not left the factory since he entered the factory about a year ago, including this year's Spring Festival, so he is naturally the most qualified to answer this question:

"At the beginning, we shared the power supply network with the adjacent Tuan County, and there were still many problems during that time, but later, Jiangcheng local area divided our surroundings into a new industrial area, and approved a special power supply line, and it is not affected by the urban power use plan, the stability of the voltage and the number of power outages have been greatly improved."

And in his mind, a relatively precise and perfect timetable was gradually formed......

However, because of the foreshadowing just now, if he refuses again, it will be too inappropriate.

If you put it aside for more than 20 years, there is almost no need to worry about this kind of problem, but in this era, we are still on the eve of a major upgrade of the power system, and although the power outage of an entire urban area cannot be said to be a daily occurrence, it can be regarded as a frequent occurrence.

Therefore, having a dedicated power line can basically avoid most of the power supply problems.

Moreover, he does hope that this legendary academician who has worked hard for Huaxia Machinery all his life and has a primary school degree can be remembered by more people, at least more practitioners:

"I propose that after the completion of the first trial production of this die forging press, use the remaining part of the production blank to erect a bust statue of Academician Shen in the Jiangzhong factory area to commemorate his efforts and contributions to this die forging press."

Chang Haonan nodded slightly:

"Since the power supply is fine, then we will tentatively ...... On May 13, the first power-on test of the equipment was performed, if no problem was found in the self-inspection and external inspection, then the hydraulic equipment began to be preheated on May 15 and officially entered the equipment start-up process, is there a problem? ”

Under the command of Chang Haonan, the progress report of each subsystem and the next work plan were summarized one by one.

The scheme design of this 75,000-ton die forging press, as well as a considerable part of the technology, are based on a 68,000-ton prestressed steel wire winding die forging press developed by Qinghua University at the end of the 80s.

"I didn't expect that in two years, I could really build this equipment from scratch from the ground up......

This is to dig into his corner......

In the end, he was rejected by Chang Haonan because he was too second.

Looking at Yan Yongnian, who saw things and thought about people, Chang Haonan felt that the effect of simple language comfort might be average.

"What is the power supply situation of the new plant, and has there been any power outage or voltage instability during the construction process?"

Chang Haonan is not prepared to hide his purpose:

"After I graduate this year, I plan to set up my own laboratory, of course, in the mode of school-enterprise cooperation between Beijing Airlines University and Torch Group, and now there is a shortage of manpower, especially graduate supervisors."

"This kind of power outage due to force majeure is acceptable, as long as it does not affect production frequently."

Then the two walked off the check-in table, one after the other.

So, after hesitating for a moment, Yan Yongnian still nodded:

"After I go back, I asked them to submit their resumes to BHA...... Anyway, having experience in this project, it shouldn't be difficult to pass ......"
