摘　　要：以满足国家法规要求为前提,在原型三轮车车架基础上调整其前倾角及前后轴间的距离,通过有限元分析,得出不同结构参数的车架在不同行驶工况不同载荷作用下的应力分布,借此判断各参数的改变对车架结构强度的影响。To meet the requirements of national laws and regulations as precondition,based on the prototype tricycle frame to adjust its castor angle and wheelbase,through finite element analysis,the stress distribution of the frame with different structural parameters under different driving conditions and different loads is obtained,then the influence of the parameters on the frame structure strength is judged.

关 键 词：三轮车车架 有限元 前倾角 轴距 强度
