In order to research contact force between mechanical components of the multi-deformable assembly and product's reliability, this paper explored the non-linear contact problems by employing the contact mechanics and the finite element method. On the basis of the Lagrange multiplier algorithm, taking multi-deformable assembly as a system, the finite element method is utilized in this paper to analyze the contact cases among deformable components in various conditions, the distribution rules of contact force, the distribution rules of stress and the deformation, with the purpose of figuring out the weakness regions and their solutions.
