Abstract: Based on engineering material science and automobile design theory, this paper uses ABAQUS software to optimize the structure of a commercial light truck glass fiber leaf spring scheme. At the same time, the acceleration data of Xiangyang test site are collected, and the strength analysis of the lightweight scheme of glass fiber leaf spring is carried out. The results show that the maximum tensile stress and compressive stress of glass fiber leaf spring meet the material limit strength The comprehensive weight reduction is up to 35 kg, and the lightweight effect is remarkable.
