Abstract

The invention relates to a device and a method for controlling the abnormal shaking of a vehicle body. The device comprises a vehicle body, bogies on the front end and the rear end of the vehicle body, an active control processor, an acceleration sensing system, an anti-yaw damping system and a vertical damping system, wherein the acceleration sensing system is arranged on the vehicle body and iselectrically connected with the active control processor; the anti-yaw damping system is arranged between the vehicle body and the bogies and is electrically connected with the active control processor; and the vertical damping system is arranged between the bogies and the vehicle body and is electrically connected with the active control processor. By use of the device, through the anti-yaw damping system and the vertical damping system, the abnormal shaking phenomenon of the vehicle body can be eliminated, the comfort of a passenger is increased, and meanwhile, a railway operation and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a device and a control method for controlling abnormal vibration of a car body. Background technique [0002] In the actual operation of domestic high-speed EMUs, the safety of vehicle operation can be fully guaranteed, and excellent operating quality can be maintained in most operating routes and operating hours. However, in some cases, due to the abnormal wheel-rail contact relationship, some abnormal vibrations will also occur. For example, the wheels of EMUs need periodic maintenance. Generally, EMUs will carry out contour repairs every 150,000 to 300,000 kilometers of running, that is, the contours after running wear will be repaired to the original design contours to ensure that the wheels Rail contact relationship is normal. Similarly, the rails of high-speed rail lines also need to polish the rail profile within a certain period. However, in some cases, such as when the profile of the track is abnormal and the wheels...
