EBE Chapter 415: Magnetic Circuit Chaos? We still have to let Engineer Li take action!
Chapter 415: Magnetic Circuit Chaos? We still have to let Engineer Li take action!
The construction of the pulse detonation engine has officially entered on track.
at the same time.
Far away in Guangdong Province, at the Yuwei Shipyard, various shipbuilding work is also in full swing.
A workshop for the construction of 10,000-ton coast guard ships.
Tang Xinghai frowned and kept fiddling with the computer, trying to make the simulated data return to normal.
However, everything seemed in vain.
No matter how he changes the data or re-programs it.
The generator's magnetic circuit is still chaotic and there is no pattern to follow.
Naturally.
They also had no way of calculating the magnetic circuit of a rectifier synchronous generator.
When other researchers in the same group saw this, they did not urge him, nor did they think that Tang Xinghai's skills were not good enough.
after all.
Let alone Tang Xinghai, I'm afraid even asking Old Yu to come here would have a hard time dealing with this.
Some researchers suggested.
"Engineer Tang, why not try Ampere's circuit law or Ohm's law of magnetic circuit?"
When Tang Xinghai heard this suggestion, he thought for a moment, nodded slightly, and decided to give it a try.
"Ampere's circuit law states that along any closed loop, the line integral of the magnetic field intensity is equal to the algebraic sum of the currents enclosed by the closed loop."
"And Ohm's law for magnetic circuits states that the magnetomotive force acting on a magnetic circuit is equal to the magnetic flux in the magnetic circuit multiplied by the magnetic resistance."
"We can give it a try and see if we can calculate the magnetic circuit of a multi-phase rectifier synchronous generator."
Now that Li Yang is not here, he is the main person in charge of the project team.
Now that we have encountered a problem, we must try every possible means to solve it.
Otherwise, it will seriously affect the research and development of coast guard ships.
Tang Xinghai was no longer indecisive and immediately issued the order.
Let's see if we can use Ampere's circuit law and Ohm's law of magnetic circuit to solve this problem and restore the R&D progress to normal.
"Team one, determine the magnetic circuit structure and current distribution immediately!"
"Groups 2 and 3 will try to perform practical calculations using Ampere's circuit and Ohm's law for magnetic circuits, respectively."
The leaders and members of the two groups immediately took orders, went to their posts as required, and began to cooperate with Tang Xinghai's work.
As for himself, he maintained a highly concentrated mind, constantly recording the data sent back by the two groups, and conducting verification, adjustment and simulation.
After half an hour.
Tang Xinghai led three groups to conduct multiple rounds of attempts, but the results were not satisfactory.
Although there were one or two times when the simulation results were relatively stable, they could not be maintained for long.
and……
There is a huge difference between the previous simulation diagram and the later simulation diagram, and it is impossible to calculate the regular magnetic circuit of the multi-phase rectifier synchronous generator.
Such a result made the researchers present feel a little depressed.
This is indeed a difficult technical problem, but they are old masters with decades of experience after all.
Despite the efforts of so many people, the problem still cannot be solved.
I feel a little frustrated.
The researchers suggested.
"Engineer Tang, why don't you call Engineer Li and invite him to come over?"
"If this problem cannot be solved, we will not be able to build the integrated power system of the coast guard ship in the future, which will greatly affect the subsequent construction plan."
"Mr. Tang has already made enough efforts. This problem is indeed a difficult one. We cannot waste our efforts on a problem that has no results!"
"..."
They looked at Tang Xinghai, and on the one hand, they were anxious to solve the problem quickly so as not to delay the research and development progress.
Simultaneously.
He was also afraid that this incident would hit Tang Xinghai and offend him.
but……
They were obviously worrying too much. Tang Xinghai was not the kind of person who couldn't stand others being better than himself.
in contrast.
For a young and talented boss like Li Yang, he has more admiration and respect in his heart, and is eager to learn and seek advice.
After Tang Xinghai tried it one last time, he sighed.
"Everyone, our skills are still not strong enough, hahahaha..."
Just a joke and everyone laughed.
Seeing his expression, which was lonely but not jealous at all, the researchers present breathed a sigh of relief.
They all laughed and joked.
"Engineer Tang, you are wrong. It's not that our skills are not good enough, but Engineer Li is too good. Who would have thought that a coast guard ship used nearly 60% of new technology!"
"Hahahaha... Although what Lao Wang said may sound a bit self-flattering, it's the truth. Engineer Li is too scary!"
"Let alone other things, the medium voltage DC integrated electric propulsion system alone is truly amazing!"
"Yes! And I think this technology is a bit of a waste when used on coast guard ships. If it can be used on aircraft carriers, wouldn't it be..."
Hearing this, the researchers' minds suddenly became active.
They saw the power of the medium-voltage DC integrated electric propulsion system from the simulation video in the design plan.
All-electric propulsion makes the entire ship very quiet, almost silent.
This is of great help for maritime navigation and naval warfare.
Make it more difficult for the enemy to detect the ship.
Also.
Ships that use a medium-voltage DC integrated electric propulsion system can quickly switch circuits within a few milliseconds in the event of special circumstances such as circuit breaks or circuit attacks to ensure that the entire ship returns to normal power supply.
And this.
This is something that other ships using AC power supply systems cannot do.
but……
The researchers did not take it for granted that this technology could be used directly on aircraft carriers.
Although the coast guard ship designed by Li Yang has an exaggerated displacement of 18000 tons, it is still far from that of an aircraft carrier.
therefore.
It is estimated that there is still a long way to go before this medium-voltage DC integrated electric propulsion system can be used on aircraft carriers.
Tang Xinghai smiled and did not join their discussion, but said.
"I'll contact Mr. Li later to see if he has time."
"Let's develop other modules first in the next few days, and when Engineer Li comes, we will solve this problem together!"
Everyone readily agreed.
After leaving the workshop and returning to the dormitory, Tang Xinghai called Li Yang and told him about the problems he had encountered.
"Engineer Li, we are not as skilled as you and cannot solve this problem."
After listening to this, Li Yang on the other end of the phone did not blame anyone.
comforted.
"Mr. Tang, don't be ashamed. This question is indeed a bit difficult."
"I'll come to Guangdong Province in two days after I finish dealing with things here."
"How about we take everyone with us to solve this problem together?"
Tang Xinghai was overjoyed.
"Then I'll have to trouble Mr. Li!"
Li Yang waved his hand.
“Learn from each other, communicate with each other, and make progress together!”
"Once these problems are resolved, the coast guard ship can be launched soon."
"Also, you need to speed up your progress. I have some equipment here that is almost finished."
"By then, these equipment will be installed on the coast guard ships..."
