Analysis and optimization on static stiffness of wedge suspension based on DOE and CAE technology
Abstract:As to the issue that the suspension system structure should be adjusted repeatedly to meet the stiffness performance requirements during the design process, the numerical simulation test on the static stiffness of trapezoidal rubber suspension is carried out using DOE and CAE technologies. The influence of structural parameters of main spring on the suspension static stiffness is studied, such as the width, length, thickness, and angle. The factors of every structural parameter are analyzed according to the results of tests, and the influence of structural parameters on the static stiffness of suspension and the corresponding regression equation are obtained. The regression equations are used to optimize the target stiffness of the sample piece, and the value of each structure parameter can be obtained quickly. It shows that the method is of high conveniency and effectiveness. The result can provide reference for the design and manufacture of wedge rubber suspension.
keywords:wedge suspension  rubber  static stiffness  main spring  optimization
