Embodiment Construction

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Traditional non-adjustable anti-snake shock absorbers are difficult to adapt to different wear states of wheels. In order to improve the adaptability of wheels under different wear levels and improve the stability of train operation, it is very necessary to develop anti-snake shock absorbers with active control. . Based on this, an embodiment of the present inve...

Abstract

The embodiment of the invention provides a control method and system of an anti-yaw damper. The method comprises the following steps of acquiring a head swinging speed of a rail vehicle framework anda stretching speed of the anti-yaw damper; judging whether the swinging direction corresponding to the head swinging speed and the stretching direction corresponding to the stretching speed are in thesame direction or opposite directions so as to obtain a judgment result; and adjusting the damping force of the anti-yaw damper according to the judgment result. According to the control method and system, the damping force of the anti-yaw damper is adjusted in real time according to the swinging direction and the stretching direction, carriage wheels with different abrasion states can be met, the stationarity requirements of the vehicle at the high speed are met, and the requirements of rapid, safe and comfortable in rail transit transportation are met.

Description

technical field [0001] The present invention relates to the field of rail transit, and more specifically, to a control method and system for an anti-snaking shock absorber. Background technique [0002] The parameter matching of the anti-snaking damper is one of the key factors for the safety of train operation. With the increase of the running mileage of the vehicle, the equivalent taper of the wheel tread increases continuously, causing the snaking frequency to increase continuously, and the required secondary rotation resistance torque is also increasing. However, the anti-snaking damper in the prior art cannot adjust the damping force, so it is difficult for the anti-snaking damper in the prior art to adapt to different wear states of the wheels, resulting in unstable and unsafe running of rail vehicles. . Contents of the invention [0003] In order to solve the above problems, an embodiment of the present invention provides a control method and system for an anti-sn...
