Abstract

Embodiments of the invention provide a control method in a semi-active anti-hunting vibration damping system, and a controller. The method includes obtaining the current running state of a vehicle; adjusting the vibration damping mode of the vehicle to a semi-active mode if the current running state is determined to be normal so that the system parameters of a vibration damping system can be adjusted in real time; and adjusting the vibration damping mode of the vehicle to a passive mode if the current running state is determined to be abnormal. The provided control method and controller can pertinently select the vibration damping mode to automatically adjust the parameters based on the running state of the current vehicle, so that turning repair periods can be prolonged, and operation costs can be reduced; and the passive mode can be automatically switched at special situations such as the out of control of bogies, so that the normal running of a train can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle vibration reduction, in particular to a control method and a controller in a semi-active anti-snaking vibration reduction system. 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 stiffnes...
