Anti-snake vibration damping system, vibration damping control method and vehicle

Abstract

Embodiments of the present invention provide an anti-snaking vibration damping system, a vibration damping control method, and a vehicle. The anti-snaking vibration damping system includes an anti-snaking vibration damper, a controller, a driver, and several acceleration sensors. The driver and The acceleration sensor is installed inside the vehicle; the output end of the acceleration sensor is connected to the input end of the controller, and the output end of the controller is respectively connected to the input end of the anti-serpentine shock absorber and the driver, The output end of the driver is connected to the anti-serpentine shock absorber; the controller determines the current state of motion of the vehicle according to the collected value of the acceleration sensor, and generates a driving signal for the A drive controls the action of the anti-serpentine damper. The embodiments of the present invention provide an anti-snake vibration damping system, a vibration damping control method and a vehicle thereof, which can select different vibration damping modes for control according to the real-time running 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
