The suspension system and its design theory and method of network synthesis based on a triangular periodic table of elementary mechanical elements, is a new problem faced by the vehicle system dynamics. According to the electrical-mechanical analogies and the principle of the mechanical network synthesis, the suspension design based on the periodic table is transformed into a network synthesis design. After the vehicle model with robust controller is established, by using the positive real lemma, suspension network synthesis is a described as a problem of design and solution of the real controller with periodic table element constraints. And then, according to the conditions of asymptotic stability of the closed-loop system, the problem boils down to an optimization problem based on BMI constraints. The higher order impedance function of the suspension structure is obtained by solving the optimization problem, based on LMI algorithm combined with genetic algorithm and Path-following algorithm. The method of reducing order and approximation is studied, and the physical realization method of low order impedance function is proposed to reduce the complexity of suspension structure and to determine the specific parameters of the suspension structure and preliminary parameters of the components. On this basis, the dynamic model of suspension system is established to simulate and analyze the performance of the suspension system. And the specific parameters of the components are determined by multi-objective optimization. Finally, the prototype of the suspension system is designed and developed by means of multi-element fusion method. The purpose of this project is to provide theoretical and technical support for the suspension system based on the periodic table and its application.
