The invention relates to a control device of abnormal shaking of a vehicle body based on an anti-hunting damper and a control method. The control device of abnormal shaking of the vehicle body based on the anti-hunting damper includes the vehicle body, bogies at the front and rear ends of the vehicle body, an active control processor, an acceleration sensing system and an anti-hunting damping system. The acceleration sensing system is arranged on the vehicle body, and the acceleration sensing system is electrically connected with the active control processor. The anti-hunting damping system isarranged between the vehicle body and the bogies and is electrically connected to the active control processor. Through the anti-hunting damping system, the control device of abnormal shaking of thevehicle body can eliminate the phenomenon of abnormal shaking of the vehicle body, increase the comfortable sensation of passengers and reduce the cost of railway operation and maintenance.
Description
Technical field [0001] The invention relates to a device and a control method for controlling abnormal vibration of a vehicle body based on an anti-snaking 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 during most of the operating routes and operating hours. However, in some cases, due to the abnormal wheel-rail contact relationship, some abnormal vibration may also occur. For example, the wheels of EMUs need periodic maintenance. Generally, the contours of the EMUs will be repaired every 150,000 km to 300,000 km. That is, the contours after running wear are re-repaired to the initial design contours to ensure that the wheels The rail contact relationship is normal. Similarly, rails of high-speed railway lines also need to be polished in a certain period. However, in some cases, such as abnormal line track profile, when...
