A theoretical model used for determining the stiffness of composite leaf springs with a main spring and an auxiliary spring

Abstract: The stiffness characteristics of composite leaf springs with a main spring and an auxiliary spring directly affect the handling stability and riding comfort of automobiles and finally determine its application value. In order to achieve precise calculation for the stiffness characteristics of composite leaf springs with a main spring and an auxiliary spring, a theoretical model, which is verified by finite element simulation and related test results, was established by using the mechanics of composite material… Show more

“…The design of spring body structure is one of the most important problems in the design theory of composite leaf spring, as the body structure primarily determines the weight, the stress distribution state, the shape of the mold cavity, and the ply scheme framework of the spring, and hence it directly affects the performance and the manufacturing cost of the composite leaf spring. Extensive efforts have been made on the structural design and optimization of the composite leaf spring body using genetic algorithm (GA) and FE approaches [22,25,[28][29][30][31][32][33]. Specifically, a GA was used to optimize the dimensions of a glass fiber-reinforced epoxy composite leaf spring with variable width, variable thickness, and equal cross-section.…”
