Abstract:
The body structure of electric bus is mainly welded by small section rectangular steel pipe, with strong bearing capacity. It has obvious advantages in structural safety, structural stability, riding comfort and other aspects, and is currently widely used in electric buses. This article takes the body framework of an electric bus as the research object, and based on the characteristics of body structure design, uses software such as SolidWorks and ANSYS Workbench to establish a parameterized bus body structure model. Taking the reliability of the electric bus body as the research objective, under the premise of meeting the overall strength and stiffness of the structure, local optimization was carried out on the electric bus body structure. Static mechanical performance analysis and modal analysis were conducted on the optimized body structure. Through comparative analysis of data before and after optimization, it was found that the optimized electric bus body skeleton met the requirements of stiffness and strength, indicating that the optimization of the body skeleton was relatively successful.
