Abstract: Light truck is an important commercial transportation tool in the national economy. Because the blue light truck has the right of way advantage, lightweight is the key path to realize the blue light truck. Based on the theory of materials and finite element, this paper uses ABAQUS simulation software to carry out the structural comparison and lightweight optimization design of battery supports of different brands. At the same time, the acceleration data of the battery support in the real state of the light truck under the road conditions of a test site are measured. According to the excitation data, the finite element model is introduced for load loading and transmission, and the CAE strength of the lightweight scheme of the light truck battery support is compared and analyzed. The results show that the performance of the battery support meets the target requirements. The weight of the lightweight scheme is reduced by 1.2 kg, and the lightweight effect is remarkable.
