Discussion on the Design of Test Loading Device for Inner Parts of Railway Vehicle Body

In this paper, a test loading device is introduced, which is mainly used to load the inner parts of railway vehicle body to verify the structural strength of the inner parts of the vehicle body. The design scheme of the test loading device is optimized, and the feasibility of using aluminum alloy and carbon steel is analyzed. In consideration of the safety of the test, carbon steel is used. The structure strength of the test loading device meets the requirement of the test, and the purpose of the structure strength test of the inner parts of the vehicle body is realized.
