The foundation brake rigging is an important part of the railway freight cars, as it is an actuator of the rolling stock for deceleration and stop to ensure essential device for running safety. The mechanism clearance of the foundation brake rigging has a great influence on the brake shoe eccentric wear in the braking and releasing process. Especially during the braking process, the contact area between the brake shoe and the wheel tread is very small, resulting in the contact area with high stress. Actual operation manifests that on the upper side of the brake shoe wear severely. In order to build and analyze the model of the mechanism with clearance, the foundation brake rigging for the rigid-flexible coupling and multi-body dynamics simulation is carried out with the RecurDyn software, which provides the flexible body analysis module-FFlex. The method of resolving the problem is proposed, which includes the original model format conversion, the model preprocessing, constructing the rigid-flexible coupling dynamics model and analyzing the simulation results, and then providing the theoretical and technical support to improve the foundation brake system for railway freight cars by analyzing the main factors of influencing brake shoe eccentric wear.
