Embodiment Construction

[0018] Combine below Figure 1~2 Embodiments of the present invention are described in detail.

[0019] The vibration monitoring and active vibration suppression method of rolling stock is characterized in that: the vibration signal of the oil pressure shock absorber in the vehicle is collected, the collected vibration signal is transmitted to the locomotive control system, and the oil pressure vibration reduction method is established in the locomotive control system. The vibration signal of the oil pressure shock absorber is the vertical coordinate, the vibration spectrum of the oil pressure shock absorber is the horizontal coordinate, and the vibration spectrum of the railway track is the vibration signal of the oil pressure shock absorber. The railway track position is the horizontal coordinate. The vibration spectrum of the shock absorber and the frequency spectrum of the railway track are monitored in real time, and the corresponding damper in the vehicle is controlled t...

Abstract

A vibration monitoring and active vibration suppression method for a locomotive vehicle comprises the following steps of acquiring a vibration signal of an oil pressure damper in the vehicle, and transmitting the acquired vibration signal to a locomotive vehicle control system; establishing an oil damper vibration spectrum taking a vibration signal of an oil damper as a vertical coordinate and time as a horizontal coordinate and a railway track road condition spectrum taking the vibration signal of the oil damper as the vertical coordinate and a railway track position as the horizontal coordinate in the locomotive vehicle control system; and monitoring the vibration frequency spectrum of the oil damper and the railway track road condition spectrum in real time, and enabling a correspondingdamper in the vehicle to actively suppress vibration according to the real-time railway track road condition spectrum signal. According to the invention, online detection of the oil damper is realized, the initiative and timeliness of locomotive vehicle control are improved, the vibration suppression damping force frequency spectrum of the damper and the railway track road condition frequency spectrum are synchronously formed, the damper actively resists locomotive vehicle vibration, and the operation stability of the locomotive vehicle is improved.

Description

technical field [0001] The invention relates to a vibration monitoring and active vibration suppression method for rolling stock, and belongs to the technical field of vibration reduction for railway rolling stock. Background technique [0002] In recent years, my country's railway technology has developed rapidly, and the speed of trains has continued to increase. The research and control of vehicle dynamics has become more and more important. In order to ensure the safety of high-speed train operation and ride comfort, vehicle dynamics control has become the main research goal. The vibration generated during the operation of railway vehicles is attenuated by the oil shock absorber. In order to suppress the running vibration of the rolling stock to the greatest extent and realize the active control of the rolling stock running vibration, the vibration reduction of the oil pressure shock absorber should be reasonably designed. It is very necessary to establish the vibration...
