Abstract
(EN)
A damping control method and device for a shock absorber of a train. The method comprises: acquiring lateral vibration acceleration of a frame of a train; determining whether or not a damping force of a shock absorber of the train matches the lateral vibration acceleration of the frame; and if not, adjusting a damping force of a variable-damping-force shock absorber of the train, such that the damping force of the variable-damping-force shock absorber matches the lateral vibration acceleration of the frame. The technical solution can be used to adjust a damping force of a variable-damping-force shock absorber of a train, and can be applied to a train equipped with a variable-damping-force shock absorber so as to improve the efficiency of damping adjustment and lower labor costs.

L'invention concerne un procédé et un dispositif de commande d'amortissement pour un amortisseur de chocs d'un train. Le procédé comprend : acquisition d'une accélération de vibration latérale d'un châssis d'un train ; détermination si une force d'amortissement d'un amortisseur de chocs du train concorde ou non avec l'accélération de vibration latérale du châssis ; et à défaut, réglage d'une force d'amortissement d'un amortisseur de chocs à force d'amortissement variable du train, de sorte que la force d'amortissement de l'amortisseur de chocs à force d'amortissement variable concorde avec l'accélération de vibration latérale du châssis. La solution technique peut être utilisée pour régler une force d'amortissement d'un amortisseur de chocs à force d'amortissement variable d'un train, et peut être appliquée à un train équipé d'un amortisseur de chocs à force d'amortissement variable de façon à améliorer l'efficacité du réglage de l'amortissement et réduire les coûts de main d'œuvre.
