摘　　要：针对客车传统模块设计方法的不足,基于广义模块化理论对客车底架进行参数化设计。利用广义结构模块矩阵对客车底架进行模块划分,结合用户需求矩阵实现总长为10.0~12.0 m同系列客车车型底架的设计。采用HyperWorks软件对所设计的系列车型整车骨架建立有限元模型,通过2种工况下强度和刚度分析验证设计的可行性。结果表明:广义模块化设计理论在客车底架的设计上具有良好的适用性;在弯曲及扭转工况下的最大应力值、整车的弯曲刚度和扭转刚度均与底架中段模块长度的改变呈现线性关系;总长为10.0,10.5和11.0m的3部车型能够满足相关设计要求。A parametric design of bus chassis with total lengths from 10.0 meter to 12.0 meter was conducted based on generalized modular forms and supported with user demand matrix.Finite element modeling of the whole bus frame was established using HyperWorks and its feasibility verified by analysis of strength and stiffness in two working conditions.The results show that generalized modular design is well applicable to bus chassis design,in which the maximum stress values,and bus bending stiffness and torsional stiffness under bending and torsion vary linearly with the changing length of the middle module of the bus chassis,and designs meet the related requirements when applying to three buses with total lengths of 10.0,10.5 and 11.0 mrespectively.
