Research on Structure and Lightweight of Automobile Seats

Abstract:

This paper starts from the design of seat frame made of lightweight, structural optimization and forming process to analyze the car seat design of lightweight. The paper analyze new aluminum alloy seat using finite element simulation analysis and are the analysis of the structural optimization design based on the results. On this basis, in order to reduce the weight of the seat frame, built design variables model with components of plate thickness, taking stiffness and the first torsion frequency of seat frame as state variables under different conditions, taking total mass of seat frame lightweight optimization goal to optimize its parameters of size structure. The seat frame not only meets the strength requirements, but also improves the utilization rate of materials, compared with the original structure; the quality is reduced by 9.6% and get better lightweight.
