摘　　要：通过有限元法计算分析电动客车实际运行中在弯曲、扭转、紧急转弯和紧急制动等典型工况下的车身结构强度与刚度,并利用ANSYS-Workbench软件平台对车身骨架结构进行拓扑优化设计,有效地降低了车身重量。Basing on the finite element method, the structural strength and rigidity of an electric bus are computed and analyzed when working at four cycles： bending, torsion, emergency turning and emergency braking. Furthermore, by using ANSYS-Workbench software platform, the body frame design of topology optimization is reached to the re- sult of reducing the gross body mass.
