The method to solve the spring stiffness of the suspension spring system by using the static mathematical model and the genetic algorithm is proposed. The static model of the spring system of the crawler-skid loader’s suspension system is established, and the conditions that the system design needs to meet are analyzed. A ladder-search algorithm based on genetic algorithm is designed and the search flow is given. The stiffness of the suspension spring is optimized through examples , Draw a curve describing the static performance of the suspension spring system, prove the correctness of the mathematical model and the feasibility of solving the algorithm. The method is simple, accurate and practical. It can provide a reference for the determination of the initial parameters of the suspension spring system of other engineering vehicles.
