In the laboratory, Ma Tian began to study the cloud car with the cooperation of Tianji.

Although the concept sounds simple, just levitate the subway train in the air and then switch the traction lead through the magneto-solid field, there are still a lot of technical details.

The first problem to be solved is the power design of cloud vehicles.

The magnetosolidate force formed by the magnetosolidity field strictly follows the magnetosolidity field formula, and the magnitude of the magnetosset force follows the magnetosolidity field equation F = ρMmK/r+m

In the formula, K is the parameter of the magnetic solidity field coefficient, which is the variable of the magnetic field at the indefinite interference frequency, r is the distance, and M m is the mass of the two.

It can also be seen from the formula that the suspended height and mass of the cloud car will determine the magnitude of the magnetosolid force on itself.

And the magnitude of the magnetism force will determine the movement of the cloud car!

If the mass of a cloud car is too large, although the magnetism is enough to satisfy, the energy to make it move will be huge.

Even if the magnetosolid force is the fifth strongest force in nature, it must obey the law of conservation of energy.

Its energy source is the magneto-solid field, and the generation of the magneto-solid field requires a continuous stream of electrical energy.

Like the disc toy made by Ma Tian, a solid-state battery is embedded in the base, which has been transmitting power and maintaining the magnetic field.

Otherwise, if there is no power, the ring will fall on its own and lose its magnetism.

Although, the amount of electricity required is relatively low.

But now if it is replaced by a cloud car of tens or hundreds of tons, this energy transmission must be considered, and the braking energy required to stop such a large object moving at high speed will also be a huge number.

Therefore, at the beginning of the design, Ma Tian should consider the balance between the quality and height of the cloud car, and allocate the magnetosolid force in an optimal solution.

This is a huge amount of data calculation, and there will be a lot of factors to consider.

The second problem to be solved is the problem of magneto-solid field interference.

Although the magneto-solid field is relatively stable and is not easy to be disturbed once formed, the materials it forms are easily disturbed, after all, most of them are composed of active metals such as iron and zinc that are easy to change.

It may not be a problem for a day or two, but after a long time, oxidation in the air can easily lead to problems with the magnetic solidification field.

Once there is a problem with the magneto-fixed field and the force changes, it will be an absolutely devastating blow to the cloud car in high-speed motion.

Like Ma Tian predicts, the speed of the cloud car can soar to more than 2000 km/h casually, this speed, not to mention a sudden braking, even if there is a small bump, for the passengers inside, it is no less than going to the ghost gate to report a way, see if the king of Hades will accept you.

Moreover, the speed of 2,000 kilometers may be an appetizer, and Ma Tian feels that the upper limit of the speed is not the problem of the cloud car itself, but the problem of how much the passengers inside can bear.

can withstand sub-light speed, Ma Tian can give you a whole section out, but this cloud car may be about to turn into a hearse.

Therefore, for this problem, Ma Tian himself has to study and improve the material, so that the magnetic solid-field material can be stable and not easy to change.

The third issue to be solved is comfort and safety.

In fact, Ma Tianda can be used to carry goods, and there is no need to think about it so much, but Ma Tian still wants to carry people, and the impact value of the brush system is used, and comfort and safety must be considered when carrying people.

Now the system has risen to 1 billion impact value to get the next gift package, this 100 million impact value has made him for nearly 2 years, 1 billion Ma Tian will not make some other products out, I don't know if it will be the year of the monkey.

Therefore, if the cloud car invented by Tianyu Xinghai can replace the high-speed rail counterpart, then Ma Tian feels that he can earn a lot of influence value.

After all, there are so many people in the country, let alone a few hundred million more influence points to him.

As long as it is a technology product, it involves security, and it definitely needs a lot of technology to solve, not to mention a high-speed flying car like a cloud car.

Of course, there are certainly more than just these three issues to consider, and there are many other issues to consider.

Ma Tian can only take one step at a time, first try a point in the city of progress, and make a more stable castrated version of the cloud car to test the water.

……

After another month in the laboratory, Ma Tiancai sorted out the first version of the cloud car plan, and asked the factory to make a small model to run the simulation test.

Just leave this directly to Ye Yuyan, a big modeler, to keep an eye on.

So in the newly built cloud car factory in Tianyu Xinghai, Ye Yuyan took people to watch the cloud car on the ground running laps there.

It is surrounded by a large number of monitoring devices and various sensors, constantly recording data, refining and analyzing models.

As for Ma Tian, he still concentrates on solving the problem of the stability of magnetic solid-field materials, which is knowledge that the system does not give, and Ma Tian has to study it himself.

When it comes to materials, there is no simple one, Ma Tian has made no progress for a week, and he almost has to add some points to add materials to Lv5 first, but he still held back, after all, Ma Tian felt that it might be better to stay and add mathematics and physics.

And Ma Tian also feels that he can toss it out without relying on the system, and this level is still there.

Another month has passed, and Ma Tian still hasn't come out of the laboratory. During this period, only Yang Koi and Li Runqi could occasionally go into the laboratory to deliver food, and the others Ma Tian were nowhere to be seen.

Hua Shuwen is also crazy in his mind to make up the reason for Ma Tian's success, and with the perseverance to conduct research retreat experiments, it is no accident that Ma Tian can have today's achievements.

Including talking to Wang Chenbo, Leng Fangguo and others, Hua Shuwen also did not hesitate to praise himself:

"I have to admire Ma Tianlian, he has been in retreat in the laboratory for two months, if I hadn't learned about him through Yang Koi and Li Runqi, I would have been a little worried about him!"

"To be honest, Ma Tian is really good, there are a few 'richest people' like him who don't have a beautiful woman as a companion, but calm down and do research every day."

……

"Yes, yes, yes!" Wang Chenbo and Leng Fangguo nodded frantically, this is also what they like about Ma Tian.

Therefore, even if Ma Tian is occasionally stunned and domineering and causes some trouble outside, they all feel like a. Except for the last time I gave Lao Mei a look, and the two of them were angry, I really didn't think Ma Tian had done anything excessive before.

After another 2 weeks, Ma Tian finally came out of the laboratory, and at the same time brought out an enhanced version of the magnetic field production manual.

Ye Yuyan has been simulating in the cloud car factory for 2 months, and it can be said that she has already had a clear idea of Ma Tian, and when she saw the new materials, she also asked the engineers to quickly use the new materials to make a new model to run circles.

And she herself stood next to Ma Tian and began to report on the simulation of the past two months:

"We take the city of progress as the sand table, and comprehensively consider the situation to establish three main lines and one peripheral line, the three main lines are mainly built around the central business districts, and the peripheral line is most suitable for the external border, which will be used as the cloud car to enter the city of progress......

In the past two months, the three trunk lines have been comprehensively tested 136824 times, with 136824 successes, with an average test speed of 60 km/h and a maximum test speed of 80 km/h......

127892 times of comprehensive tests on the periphery, 127892 times of success, the average test speed reached 4600 km/h, and the maximum test speed was 12000 km/h......"

(Acceleration is the most critical factor affecting the human body, and our human body can adapt to a speed of 12,000 kilometers.) After all, the rotation of the earth is equivalent to sitting on the ground and traveling 80,000 miles a day, but our human body is very weak in acceleration, such as a 100-kilometer acceleration sports car, the fastest acceleration can reach 1g, and we ordinary people will be uncomfortable.

Therefore, it is not the most important thing that the cloud car can reach a speed of 12,000 km/h, the most important thing is the acceleration impact of acceleration, deceleration, and cornering, but now the cloud car can be tested in the factory, and it can basically run by the way) (end of this chapter)
