摘　　要：运用有限元软件建立高速列车CRH3承载结构有限元模型,分析了当承载结构发生改变时使车体模态频率达到最大值的车体侧墙高度、车窗位置和边梁厚度.结果表明,在原承载结构基础上动车侧墙高度降低50mm、车窗距地板的高度降低50mm、边梁厚度不变时车体模态频率最大;在原承载结构基础上拖车侧墙高度和车窗距地板的高度保持不变,边梁厚度变为3mm时车体模态频率最大.A finite element model of high-speed train CRH3＇ bearing structure is built by a finite element software;the side-wall＇ height,window position and side beams＇ thickness is analyzed,when the bearing structure changes and the model frequency reaches maximum.The results show that the model frequency of the car EC01 reaches maximum when reducing the side-wall＇ height by 50mm and the height of window above the floor by 50mm,side beams＇ thickness is not changed;the model frequency of the car TC02 reaches maximum when the side-wall＇ height and the height of window above the floor are not changed,side beams＇ thickness is 3mm.
