Abstract: The leaf spring is a mechanical system with coupling of contact nonlinearity and large deformation nonlinearity. Based on the strong nonlinear solver of Abaqus-CAE, this paper reproduces the road test cracking problem of the leaf spring rear axle system via simulation. The results show that the quasi-static simulation analysis of the finite element model of the leaf spring rear axle system under the deep pit condition yields results highly consistent with the actual road test performance; by optimizing the length and fitting clearance of the auxiliary spring, the stress of the leaf spring is reduced by 33%. This method can effectively simulate the structural stress distribution characteristics of leaf springs, providing a rapid and effective analytical approach for the structural design of leaf springs.
