摘　　要：混合动力客车能适应节能环保的要求,但目前大多数混合动力客车是通过传统油车改造而来,其附加的动力系统和电池系统对车身结构强度和刚度的影响与传统油车不同,借助有限元方法通过分析该车型主要的承载部件车身骨架在危险工况下的静态性能分析,分析骨架结构在危险工况下的应力和变形,找出结构设计不合理的部位,为后续车型的改进设计及轻量化设计提供参考依据。Hybrid electric buses can meet the requirements of energy saving and environmental protec-tion,but most of hybrid electric buses are transformed from oil buses.The influence of the hybrid elec-tric bus's additional power system and battery system on the vehicle body structure's strength and stiff-ness is different from that of the oil bus.The static performance of the body frame was analyzed with fi-nite element method.The stress and deformation of the structure were analyzed under dangerous condi-tions.The unreasonable parts of structural design were found.The results provide a reference for im-proved design and lightweight design.
