Chapter 417 Distributed Magnetic Circuit Method!
Hearing Li Yang's words, Huang Fugui smiled meaningfully.
"Understood, Chairman!"
To be honest, Huang Fugui was quite surprised when he saw that South Korea actually expressed its intention to purchase from them.
What I thought of next was what Li Yang had just said.
Anyone who knows the Korean people knows that the only thing that is toughest about them is their mouth.
and……
The chaebols in South Korea are rich and powerful.
Since they want to buy it and also want to give it to the Eagle Army stationed in South Korea, there is naturally no problem with it being a little more expensive.
After understanding Li Yang's intention, Huang Fugui took the initiative to say goodbye and said he would go and make the arrangements.
He knew that Li Yang was going to another workshop later.
That workshop is a state-level confidential shipbuilding workshop.
Relying on his relationship with Li Yang, he wanted to go in with him for a tour and the other party would definitely have no objection.
But Huang Fugui is able to serve as the main person in charge of the sea fishing boat, so he still has some basic vision.
After he left, Li Yang and Tang Xinghai came to the outside of the shipyard workshop.
After checking according to the rules and regulations, enter the workshop in turn.
After putting on work clothes, Tang Xinghai took Li Yang inside.
Li Yang asked.
"Except for the few issues you mentioned a few days ago, are the rest of the processes going according to plan?"
Tang Xinghai nodded.
"Yes, the rest of the coast guard ship's components are being produced and constructed in an orderly manner."
"It is estimated that it will be completed in another half a year!"
This speed can be said to be very fast.
Li Yang nodded slightly.
This speed is in line with my plan.
Normally, it would take at least four to five years to build a ship this big.
That's why it's so fast now.
On the one hand, there are many workers involved in the construction, and secondly, the drawings are very detailed.
Furthermore, many component manufacturers have received orders from their superiors to be the first to meet Yuwei’s component needs.
Thanks to the cooperation of various departments, this coast guard ship is expected to be completed and conduct sea trials within two years.
Conversation room.
Tang Xinghai took Li Yang into the workshop. When the workers who were busy at their posts saw Li Yang, they stopped their work and greeted him excitedly.
"Hello, Mr. Li!"
"Mr. Li, long time no see!"
"..."
Li Yang smiled back and returned the greetings one by one.
After briefly chatting with many workers, he came to the workshop where the problem occurred.
Tang Xinghai introduced.
"We tried to use the loop law and Ohm's law of magnetic circuit to determine the magnetic circuit of the multi-phase rectifier synchronous generator and then perform magnetic circuit simulation, but the results were not satisfactory."
"Either the magnetic circuit is not obvious, or it is unstable."
Li Yang observed the circuit conditions and component structure to check whether the problem was caused by hardware.
After confirming that there were no problems with the hardware, they turned to look at their simulation tests from the previous few days.
After a while, he discovered the problem.
"In principle, both of your methods are fine, but there are some problems when used on multi-phase rectifier synchronous generators."
"These two methods are mostly applicable to single-phase or three-phase generators to stably test the magnetic circuit."
"So, to calculate the magnetic circuit of this multi-phase rectifier synchronous generator, we can use the distributed magnetic circuit method!"
Tang Xinghai frowned, with some confusion on his face.
“Distributed magnetic circuit method?”
obviously.
He didn't quite understand such an approach.
The researchers surrounding them were equally confused.
"What is this new method? Why have I never heard of it before?"
"Distributed magnetic circuit method, this..."
"Did Mr. Li create this himself?"
"..."
Discussions gradually arose, and it was almost the first time that everyone had heard of the distributed magnetic circuit method mentioned by Li Yang.
See this.
Li Yang spoke with a smile.
"It's normal that you haven't heard of this method. Strictly speaking, this should be a deformation of the loop law and Ohm's law of magnetic circuit."
He took this opportunity to briefly introduce this new calculation method.
“The basic principle of the distributed magnetic circuit method is to treat the part of the motor with relatively uniform magnetic field density as a unit and calculate the unit magnetic permeance.”
"And based on the similarities between magnetic circuits and electrical circuits, each node is connected with an equivalent magnetic permeance to form a magnetic permeance network diagram."
After listening to Li Yang's explanation of the distributed magnetic circuit method, Tang Xinghai and others immediately understood.
“So this is the method.”
"In this way, the distributed magnetic circuit method can avoid a lot of rough assumptions and empirical formulas, and has higher calculation accuracy and reliability than traditional algorithms."
After thinking about it for a while, he quickly understood the benefits of this method.
Tang Xinghai looked at Li Yang with even more admiration.
This method seems easy, but it actually requires a huge amount of knowledge and rich experience.
After Tang Xinghai's explanation, the other workers present suddenly understood.
The method is not very profound, it is more about a change in thinking and a comprehensive understanding.
But even so.
There are thousands of people in the factory but no one could have thought of it!
Everyone praised him.
"Li Gong is a great talent!"
"I never thought that a simple change of thinking could lead to a new method that can perfectly solve the problem of magnetic circuit simulation."
"The gap between us and Mr. Li is like a firefly and the bright moon!"
"Mr. Li, how did you come up with such a clever method?"
"..."
They had worked with Li Yang for some time before and knew each other's character.
and so……
They were very serious when Li Yang was teaching them.
Now when they communicate with each other, they seem very relaxed.
Ask whatever comes to mind.
Li Yang was happy to see such a scene and also liked this atmosphere.
Scientific research requires free expression of opinions so as to pool the wisdom of all parties.
"How did you come up with it?"
"If I say that I suddenly had an idea, would you believe me?"
He quipped.
Never thought.
They all nodded.
"Believe it! Believe it too much!"
"It's normal for researchers to have flashes of inspiration. It's not surprising that Mr. Li came up with this idea."
"There is no such thing as a flash of inspiration. It's just that I dream about what I think about during the day!"
"Hahaha……"
After a few minutes of friendly communication, Li Yang began to assign tasks.
"Now that the method has been determined, let's actually put it into practice?"
The workers were thinking the same thing and nodded.
Li Yang ordered.
"First, we need to build a model and divide the parts of the motors with uniform internal magnetic flux density into several units. The magnetic permeability of each unit is calculated based on its geometric characteristics and material properties."
"Which group is responsible for this?"
As soon as Li Yang finished speaking, several groups raised their hands.
See this.
He picked a group at random.
Then he continued to give orders.
"Network construction, connecting each unit through equivalent magnetic conduction to form a magnetic conduction network diagram..."
"Coupled calculation, coupling the end circuit equation of the motor with the magnetic field equation, solving the magnetic field distribution and circuit parameters through numerical methods..."
