Why do roller coasters run so fast? It was the linear motor. During the summer vacation, the playground must be one of the most densely populated venues. Children are full of novelty about the playground. Adults want to release pressure on the playground. Among the many amusement events, the roller coaster is a popular king. A roller coaster with speeds of hundreds of kilometers per hour can bring excitement and excitement to the experimenter.
I don't know if we 've ever thought about a problem like this, about a kilometer long orbit, a few tens of meters high, it takes only a few seconds to achieve speed from zero to more than a hundred kilometers, without power devices, without a steering wheel. How does the roller coaster work?
Yes, the roller coaster itself does not have a power device. Usually, it climbs slowly along the slope to a fixed height first, or uses a large thrust to launch it. This is the two kinds of power of the roller coaster. In this period, the small series of linear motors are to be shared with everyone is another, that is, through the catapult to obtain large thrust.
The so-called catapult, like the catapult we played when we were young, uses catapults to launch stones. It is fast and powerful. Scientists have used the principle of catapult to invent a variety of catapults for launching roller coasters. Among them is a new catapult, the electromagnetic catapult.
According to the knowledge of the linear motor, electromagnetic ejection refers to the launch of an object that is launched without its own power device, and the use of electromagnetic force as an acceleration means to obtain enough motion energy by the power given by the launcher. A launch method.
In the entire electromagnetic ejection system, the ejection motor is the core component of the electromagnetic ejection system. It is an execution component that converts the input energy into kinetic energy, thereby accelerating the projectile body to a specified ejection speed within a fixed distance. At present, the motor used in electromagnetic ejection system is mainly linear induction motor and linear permanent magnet motor. The linear induction motor has the advantages of simple secondary structure, but the thrust density, efficiency and power factor of the motor are low; The linear permanent magnet motor has the advantages of high thrust density and high efficiency. Both linear induction motor and linear permanent magnet motor belong to linear motor.
