The invention relates to a vehicle body abnormal-vibration controlling device and method based on a vertical shock absorber. The vehicle body abnormal-vibration controlling device comprises a vehiclebody, bogies, an active control processor, an acceleration sensing system and a vertical vibration reduction system, wherein the bogies are arranged at the front end and the rear end of the vehicle body; the acceleration sensing system is arranged on the vehicle body, the acceleration sensing system is electrically connected with the active control processor; and the vertical vibration reduction system is disposed between the bogies and the vehicle body and is electrically connected with the active control processor. According to the vehicle body abnormal-vibration controlling device, the abnormal vibration phenomenon of the vehicle body can be eliminated through an anti-crawling vibration reduction system and the vertical vibration reduction system, passenger comfort is increased, and railway operation and maintenance costs are reduced.
Description
technical field [0001] The invention relates to a device and a control method for controlling abnormal vibration of a vehicle body based on a vertical shock absorber. 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 ...
