The electric energy is used as energy, the cost is far lower than that of a chemical propellant, the controllability is strong, and objects can be accelerated to a high speed. The high-speed electromagnetic propulsion device can be applied to a plurality of fields such as traffic, logistics, aerospace, military and the like.
The vibration damping slipper is a key component of a high-speed electromagnetic propulsion device. The high-speed electromagnetic propulsion device restrains all degrees of freedom except the course through the vibration reduction sliding shoes buckled on the rail heads of the sliding rails, so that an object can only advance along the sliding rails. The damping sliding shoes are required to be ensured to be not separated from the sliding rail, but to keep a certain gap with the rail head of the sliding rail, so that the sliding shoes can smoothly pass through the sliding rail.
In the moving process, the high-speed electromagnetic propulsion device bears not only complex electromagnetic loads such as propulsion force, braking force, guiding force and the like, but also aerodynamic force/torque generated in high-speed movement, wherein the loads are dynamic loads, are transmitted to the slide rail through the vibration reduction sliding shoes, and generate impact and vibration between the vibration reduction sliding shoes and the slide rail. Meanwhile, due to the irregularity of the slide rail, when the electromagnetic propulsion device moves on the slide rail at a high speed, random vibration generated by contact, friction and collision between the sliding shoes and the slide rail is transmitted to the electromagnetic propulsion device, and the vibration affects a magnet on the electromagnetic propulsion device and needs to be subjected to certain vibration reduction treatment. Therefore, the damping sliding shoe is designed to have enough rigidity and strength on one hand, support and guide the electromagnetic propulsion device and transfer the load between the electromagnetic propulsion device and the sliding rail; meanwhile, the vibration reduction device also needs to have a certain vibration reduction function, so that the vibration level transmitted to the electromagnetic propulsion device is reduced.
The level of vibration of the electromagnetic propulsion means increases sharply with increasing speed of movement. The traditional electromagnetic propulsion device has low speed, generally only has speed of dozens of meters per second, has no prominent vibration condition and does not need to be designed for vibration reduction. Therefore, there is no suitable vibration damping design in the prior art to achieve vibration damping of high speed electromagnetic propulsion devices.
