Research on Brake Performance Attenuation of APM Vehicles

Abstract：In order to identify the cause of the emergency brake reduction occuring in some vehicles in the process of operation and maintenance， an analysis model for the brake torque of APM vehicle's drum brake was established. The cause of the brake deceleration reduction was studied and analyzed， and through friction performance tests and 1∶1 bench tests， experimental verification was carried out and a solution was put forward， whose effectiveness was verified by on-site testing.

Keywords：APM; brake performance; attenuation; test
