Mechanical parking systems are widely used special electromechanical equipments. With the increasing interests on strength safety, it was becoming a hot spot to achieve its strength properties precisely. Based on Timoshenko beam theory, a mechanical parking system was simplified to a two dimensional model, and strength calculation was performed with analytical method. Furthermore, finite element method was adopted to calculate the strength properties of this mechanical parking system, and the maximum Von Mises and shear stress were approached. By comparison with experimental stress analysis, the finite element analysis was precise, which showed a potential application in practical engineering.
