Abstract: This paper takes Pro/E as the modeling platform and Midas NFX as the analysis platform, modeling and finite element analysis of the leaf spring of trackless rubber wheeled vehicle, the stiff character of leaf spring used on the trackless rubber-tyred vehicle has been carried. We set contact relationship of the spring leaves as general and sliding contact in the nonlinear large deformation analysis. The contrast between the analysis result and experiment result has been carried and the validity of the finite element analysis is verified. The analysis result can provide the data foundation for application of spring leaves in the mine trackless rubber-tyred vehicle.
