Cities: from Heavy Locomotives to Industrial Overlords

This kind of originality is not only original in this parallel world, but also original on earth.

To put it simply, Su Qin didn't want to copy the heavy locomotives on the earth to appear in this parallel world, but wanted a true original design sound to spread out his own model of heavy locomotives.

Therefore, if there is no problem with the designs of Su Ruixue and Lu Junyi, there is no problem with using their designs.

After all, their designs are quite good.

Of course, there will be problems when designing the shape of a heavy locomotive for the first time.

Lu Junyi and Su Ruixue couldn't help but be overjoyed when they heard this.

Because if you can see the production of the products you designed, then it is a very proud and joyful thing.

Su Ruixue: "Brother, tell me what's wrong with our design draft, we'll go back and revise it."

Su Qin seriously looked at the design draft of the two and said, "You should design a street car!"

"Street cars pay more attention to ergonomics, and aerodynamics are relatively less demanding. After all, street cars require driving comfort, not wit and speed."

"So the fuel tank of the street car you designed requires a proper proportion. As long as the fuel tank is a little higher, it will be more beautiful."

"At the same time, the seat is not deep enough, and the fuel tank is not high enough. It should be too squat to ride, the riding position is not good, and it is not easy to drive."

"The appearance characteristics are not well grasped, and it looks crooked."

Both Su Ruixue and Lu Junyi listened very seriously.

They are professional design majors, and they are also very talented in the design industry, but they still don't have as much understanding of the design of heavy locomotives as Su Qin.

There is no doubt that Su Qin still has absolute authority in the field of heavy locomotives.

Su Qin looked at Su Ruixue and Lu Junyi and said, "I tell you, the biggest difference between a motorcycle and a car is that the lines of the car design may not have much to do with the riding posture, but the lines of the motorcycle design are serious. affect riding position.”

"Therefore, the rear end of the overall fuel tank should not be too low, and at the same time, it should not interfere with the driver's head. The fuel tank, fairing and seat should be designed to match each other to achieve a perfect sitting position."

"In addition, the fairing should not be too low and flat, and the front end of the fuel tank must be slightly concave to avoid hitting the chin. The overall riding is upright, not on the stomach."

Su Ruixue looked at the manuscript of the heavy locomotive he designed, nodded and said, "In this way, there are indeed certain problems."

Lu Junyi also said, "Yes, we ignored these issues."

It can be said that the design of the heavy locomotive designed by Lu Junyi and Su Ruixue is not a big problem even if it is directly produced.

It's just that for Su Qin, who is pursuing the ultimate, the requirements are higher.

Su Qin said: "By the way, there is another issue to consider when designing a heavy locomotive, that is, the rigidity of 0-0."

Rigid 0-0 sense?

This word made the two women stunned for a while.

They have never been exposed to the word.

Lu Junyi asked curiously, "Su Qin, what is a rigid 0-0 sense?"

Su Qin explained: "Rigidity refers to the degree of resistance to deformation. In the case of the frame, it is the degree to which it is not easily deformed. If the rigidity of the frame is increased, the rider will also feel the hardness and firmness. "

"But if it is raised too much, it will become stiff, hard to bend, and it will feel very heavy. It will even make the rider feel uneasy because it is not easy to transmit the reaction of the vehicle."

The design of the heavy locomotive is the design of the whole vehicle, which will definitely involve the entire frame.

This is the big frame.

Rigidity, in terms of the frame, is the degree to which it is not easily deformed.

Su Qin began to explain from the perspective of a professional knight: "The most important thing about rigidity is overall balance."

"Take a common example to explain, we can often see the words in the article to increase the rigidity of the frame, but if every revision of the car model is only to increase the rigidity, then the car will become stiff. Bang Bang."

"So the most important thing is actually the balance of rigidity. Generally, after the longitudinal rigidity of the frame is increased, the lateral rigidity and torsional rigidity tend to weaken."

"Improving the longitudinal rigidity of the frame can improve the stability and ground contact during braking, and moderately reducing the lateral and torsional rigidity can also improve the lightness and security when the body is tipped over."

"As a knight, the rigid 0-0 feeling that I feel is not only the rigidity of the frame, but also changes due to the rigidity of the rocker arm and the way the engine is fixed."

"The shape of the street car you designed is relatively slender, so the main frame should be a single-backed frame, so in order to ensure the necessary rigidity, while maintaining the rigidity of the cross section, the engine is also used to maintain the rigidity balance, and to reduce the vibration The rigidity near the arm axis can make the lateral rigidity softer and at the same time improve the flexibility of the suspension action.”

"Not only that, the rigid 0-0 feeling will also change the control feeling felt by the rider due to the adjustment of the shock absorber and the characteristics of the tires. This is the rigid 0-0 feeling."

"What the vehicle should pursue is the overall rigidity balance!"

"So you guys should know how to design the whole frame, right?"

The heavy locomotive frame designed by Su Ruixue and Lu Junyi is not a big problem, but for Su Qin, who pursues the ultimate, he must pursue the rigid 0-0 feeling in heavy locomotives.

The heavy locomotive designed in this way is definitely an extreme heavy locomotive.

Chapter 207 Original Independent Model: Feiyue G800JC (The sixth update, please subscribe)

Feiyue 450J is a military motorcycle and the first original model of Feiyue Group.

However, the overall model and part of the frame and design of the Feiyue 450J are related to the design of the Spring Breeze 250NK.

Although the original part occupies more than 85%, 25% still belongs to Chunfeng 250NK.

But this time, the heavy locomotives designed by Su Qin, Su Ruixue and Lu Junyi are completely original design from the inside out, and it can be said to be the first 100% original product model.
