Taking L-C combined brake beam as an example,this paper proposes the control law for the optimum design of brake beam body under the equivalent life principle and suggests that overload on the end of the strut is the main reason of such failure by analyzing the failure modes of the brake beams on freight cars.

The application of flexible organizations on the checking machine for the brake beams of trains;

Study on the Experiment Method of Combined Brake Beam on Railway Freight Car;

The paper deeply studies L-C brake beam of freight car and finds some questions about it in the way of design and technique through analysis of the failure happened on L-C brake beam.
