Anti-yaw vibration attenuation system, vibration attenuation control method, and vehicle

Abstract

The embodiment of the invention provides an anti-yaw vibration attenuation system, a vibration attenuation control method, and a vehicle. The anti-yaw vibration attenuation system comprises an anti-yaw vibration attenuation device, a controller, a driver and a plurality of acceleration sensors, wherein the driver and the acceleration sensors are installed in a vehicle; the output end of each acceleration sensor is connected with the input end of the controller; the output end of the controller is independently connected with the anti-yaw vibration attenuation device and the input end of the driver; the output end of the driver is connected with the anti-yaw vibration attenuation device; and the controller determines the motion state of a current vehicle according to the collection value ofeach acceleration sensor, and generates a driving signal according to the motion state of the current vehicle for the driver to control the motion of the anti-yaw vibration attenuation device. By useof the anti-yaw vibration attenuation system, the vibration attenuation control method, and the vehicle of the system, which are provided by the embodiment of the invention, can carry out control byselecting different vibration attenuation modes according to the real-time motion state of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle vibration reduction, in particular to an anti-serpentine vibration reduction system, a vibration reduction control method and a vehicle. Background technique [0002] The anti-snaking shock absorber is a key component that affects the stability of train operation. When the train is running in different states, the parameter requirements for the shock absorber are also different. [0003] In the existing technology, there are more and more cases of trains running across lines, across countries, and across regions, and the parameters of shock absorbers are becoming more and more diverse. Active shock absorbers need to be compatible with the needs of different lines, and the vehicle During the whole overhaul cycle of the system, the parameter requirements of the anti-snaking damper are also different. For example, if the taper of a new wheel is small, the anti-snake shock absorber needs to exhibit s...

AI Technical Summary

Problems solved by technology

Existing trains cannot be adaptively adjusted when running on different treads. If the vibration reduction system provided by the existing technology is continued to be used, when the train runs on a curve, the angle of attack between the wheels and rails becomes larger, which increases the lateral force of the wheels and rails and affects The safety of train operation, thus limiting the running speed; at the same time, the excessive angle of attack will make the wheel and rail wear very seriously, increasing the operation and maintenance cost
