    摘要: Provided is a method for controlling an anti-yaw damper, including: obtaining lateral acceleration signals of a frame and performing a first preprocessing on the lateral acceleration signals; obtaining a pressure difference between two chambers of an anti-yaw damper piston and performing a second preprocessing of the pressure difference; obtaining an MPPT algorithm objective function value at the current moment and an MPPT algorithm objective function value at the previous moment according to first preprocessing results and second preprocessing results, and comparing the MPPT algorithm objective function value at the current moment with the MPPT algorithm objective function value at the previous moment; and controlling the adjustment direction of an electromagnetic proportional valve of the anti-yaw damper according to the comparison result. According to the method, the damping force of the anti-yaw damper can be adjusted in real time, therefore the adaptability of the damper in different wheel wear conditions and the kinetic stability of a motor train unit are improved. Also provided is an apparatus for controlling an anti-yaw damper.

    摘要: An active control anti-yaw damper (100) is provided. When a piston (2) of the active control anti-yaw damper (100) reciprocates inside a hydraulic cylinder (1), an interior of the hydraulic cylinder (1) is divided into two cylinder blocks (PA, PB) which communicate with an oil reservoir through two main oil lines respectively to form a primary loop between the hydraulic cylinder (1) and the oil reservoir; a reversing valve (PV3) is installed between the two main oil lines and the oil reservoir and is configured to change a flow direction of the primary loop when the active control anti-yaw damper (100) is in an active mode and adjust a displacement of the piston (2) within the hydraulic cylinder (1).
