Strength analysis of the wheel considering wheel-axle contact based on the static substructuring technology

In this paper,with the application of the static substructuring technology in the finite element analysis,fast solving of the strength of the wheel when considering the contact nonlinear of the wheel-axle interference fit joint was achieved with limited computation resources. The calculating result shows that using this method,the stress distribution of the wheel with the applying of the multi-load can be determined more truly and precisely.
