Chapter 235 Even the dumbest person can learn Maxwell's equations?

Li Younan possesses top-notch electrical skills.

In fact, the skills assigned by the system, if applied to daily life skills or physical skills, are still within the scope of human comprehension.

However, when placed in a skill field that requires a lot of time for thinking and research, it becomes somewhat abstract.

In fact, these skills are extremely fair, and the level achieved by each skill is similar in the field in which they are located.

For example, Li Younan's cooking skills are at the first level. Although he is only at the first level, his cooking is exceptionally delicious. However, since cooking itself is not very difficult, the difference between the top and the beginner is not noticeable to most people.

The upper limit for cooking skills is only 10, so even if you reach 90% within this limit, it seems like you're only a few points away from the 20% or 30% beginner level.

However, in fields like electrical engineering, the upper limit is outrageously high. If the upper limit is 1000, then Li Younan is several hundred points ahead of someone who has just entered the field, which is extremely frightening in the eyes of ordinary people.

At this point, Li Younan's electrical skills were not much different from those of the top engineers who developed this suspension system.

He only lacks experience in participating in projects, but there are basically no barriers to adaptation based on understanding.

Li Younan stayed at BYD's headquarters for three or four days, and no one knows what he talked about with BYD's engineers.

As he left BYD, he excitedly filmed a video saying, "Guys, my secondary suspension is finally settled. Do you guys know the Yunlian Z? It's the fully active electromagnetic suspension that's installed on the BYD Yangwang U7. With this thing, my entire cabin can be perfectly integrated with the Unimog's chassis. I've already had a deep conversation with BYD's engineers, and they will help me customize an electromagnetic suspension system."

After turning off the video, Li Younan couldn't help but feel a little excited.

In fact, although BYD eventually agreed to customize this exclusive version of the electromagnetic suspension for him, the process was not so smooth.

He talked to the engineer for a long time, pleading and persuading him until he finally succeeded in convincing the manager he admired.

What's even more exciting is that Li Younan didn't have to pay for this electromagnetic suspension system; of course, the condition was that he would help promote BYD.

For science students in this field, the value of this linear motor electromagnetic suspension is self-evident; everyone knows how advanced its technology is. It's no exaggeration to say that this suspension is currently the best active electromagnetic suspension in the world.

However, both domestically and internationally, only a very small number of people pay attention to and understand technology, so BYD still hopes to have some special channels for publicity.

Therefore, if Li Younan can successfully adapt the Yunlian Z as the secondary suspension for the Unimog, it would be a good opportunity for them to enhance brand awareness.

Their main concern was the compatibility issue. After all, to transplant the electromagnetic suspension from the vehicle to the connection between the Unimog and the housing, the entire housing would need to be redesigned, and the control program would need to be reprogrammed.

However, after Li Younan had in-depth conversations with their team's engineers for three days, all the problems were solved.

In fact, when Li Younan was leaving, the chief engineer couldn't help but extend an invitation to him, hoping that he would join their research institute.

Li Younan responded cheerfully, "If I ever accidentally film a video that causes a building collapse, I'll ask you guys to take me in."

That was obviously a joke.

The engineers looking up at the team felt a little regretful, but they didn't want to try to persuade them to stay any longer.

Li Younan returned to Chengdu and patiently waited for half a month before the brand-new, customized Yunlian Z was finally shipped to his Unimog factory.

Before that, Li Younan hadn't been idle. He used a computer to create a model based on the electromagnetic suspension design, and then commissioned a motorhome manufacturer to modify his motorhome body using the best materials. This way, when the brand-new Yunlian Z was transported over, it could be installed directly.

In fact, when Li Younan completed the modeling and modification of the container, the designers and workers at the RV factory were quite puzzled.

Because the structure of the box he designed is not so much difficult to adapt to any secondary suspension on the market, but basically has nothing to do with it.

While everyone was surprised by Li Younan's proficiency in using the modeling software, they couldn't help but remind him at the end: "Mr. Li, to be honest, in all my years in this industry, I've never seen a suspension system with this kind of structure. May I ask, what's the background of your equipment?"

Li Younan still didn't explain until the electromagnetic suspension system arrived, leaving everyone in the factory stunned.

As an industry professional, I am well aware of the technical sophistication of this electromagnetic suspension system.

However, the more one understands this, the more absurd it seems.

What does this feeling resemble?

For example, a laser cannon travels at the speed of light and cannot be dodged. Anything that moves is no different from something that is stationary in front of a laser cannon... No matter how fast you are, can you be faster than the speed of light?

Theoretically, anything appearing within the laser cannon's field of view is guaranteed to hit, and because the power can be set, it can also ensure that nothing other than the target is damaged when it hits the target.

These advantages... in a sense, actually perfectly meet the need to kill mosquitoes.

but!

but!

If someone actually used a laser cannon to kill mosquitoes, how would people view this?
You'd just think that's nonsense, right?
When Li Younan brought over this electromagnetic suspension system to use as the secondary connection suspension for the Unimog, that's how they felt—isn't that nonsense?
Electromagnetic suspension is not unsuitable as a secondary suspension; on the contrary, it is perfectly suited!
All its advantages, such as millisecond-level response, active safety features, high load-bearing capacity, and charging during vehicle vibration, perfectly match the needs of a secondary suspension system in a motorhome. Imagine if this electromagnetic suspension system were truly perfectly adapted to the motorhome body; inside, it would truly become a suspended cabin, completely free of bumps.

But would it really be used as a secondary suspension?

No matter how much other people's RV suspension is touted as being amazing, it's still just a spring structure.

Looking at Li Younan's... it really has the aesthetic appeal of using a laser cannon to swatt a mosquito...

But after the initial shock, there was more skepticism.

That means this electromagnetic suspension system isn't something that can be used simply after physical installation; it also requires complex adjustments.

Who will handle this?
The next period of time was Li Younan's performance time.

……

Debugging the electromagnetic suspension of this Yunlian Z is indeed not an easy task.

Although he had already upgraded and modified the housing to perfectly adapt it to the electromagnetic suspension in terms of structure, the essence of the entire electromagnetic suspension is its control system. The integration and matching logic of the system needs to be completely redesigned, which requires a very deep understanding of the structure of the entire system.

However, this was not a difficult problem for Li Younan.

When he was preparing to start the renovation, he specifically asked a young man in the factory who had nothing to do to help him film a video.

While making adjustments, Li Younan explained to the audience off-camera: "First of all, we need to upgrade and modify the energy system."

"Originally, we were going to install an energy system in this RV, because you can't just use oil in the wild."

"The energy consumption of this electromagnetic suspension is far beyond what the small batteries in the Unimog can provide."

"We are using a 50 kWh blade battery pack here, which is also the energy center of our entire vehicle."

"In addition, there is a small generator, and this is its fuel tank. This generator is for storing gasoline and has a capacity of 40 liters."

"In extreme cases, this generator alone can provide us with about 120 kilowatt-hours of electricity. Theoretically, that much electricity would be enough to easily live in the wild for half a month."

Li Younan's installation process was not as quick as expected. After all, it was an extremely complex and systematic task, and most people simply couldn't understand it.

The biggest challenge is actually optimizing the electromagnetic drive algorithm so that the system can capture the displacement difference caused by the 15-30 degree torsion of the beam in real time and dynamically offset the stress through vector electromagnetic force, thus preserving the original vehicle's torsional redundancy while achieving stable box body posture.

Despite having electrical skills, Li Younan still needed to rely on himself for most of this part of the work.

This was also the first time he, as a programmer, had relied on his own abilities after acquiring the system.

Li Younan is not bad at this aspect either.

Some people think that cars with mechanical structures are more technically difficult, but that's precisely because mechanics are understandable, while the technical difficulty of electric motors is something that ordinary people simply cannot comprehend.

Next, Li Younan demonstrated in detail to the audience off-camera the system integration and matching modifications, as well as the design of the entire heat dissipation system.

Of course, the RV factory's professional equipment and workshops helped him a lot during this process. Li Younan also reciprocated by mentioning many times: "The equipment at this RV factory is very professional. I'm not saying this as an advertisement. If you are interested in ordering an RV, you can really come here."

These few words deeply moved the RV factory manager.

Thanks to the system's skills, the complex electromagnetic calculation formulas in Li Younan's mind became very simple.

When he is fully immersed in his work, his attention is highly focused, his brain is working at lightning speed, and he even loses some sense of the boundary between complex and simple knowledge.

One day, while Li Younan was adjusting the compatibility of high-precision sensors and control systems, someone in the live stream asked, "What exactly is the streamer doing? Can anyone explain this to me?"

Li Younan, feeling somewhat drowsy from prolonged high-intensity work, casually explained, "Let me briefly explain the principle behind this debugging process. Based on the Lorentz specification of electromagnetic potential in Maxwell's equations, the linear motor of the Yunlian Z achieves vector synthesis of the Lorentz force in a time-varying electromagnetic field. This is achieved through the coupling relationship between the vector gradient and the time derivative of the scalar potential, thus enabling the decoupled control of the suspension stiffness and damping across the entire domain..."

Li Younan felt he had explained things very clearly, but the live stream was silent for a moment before the chat exploded with comments: "What is he mumbling about?"

Li Younan then realized that he seemed to have inadvertently confused the difficulty of this complex knowledge with elementary school mathematics.

But it's too late now...

He blinked, slowly lowered his head, and murmured, "Even if someone is stupid... can't they learn Maxwell's equations?"

After saying that, he continued with his work.
