摘要： 为降低专用车重量、提高组装效率，新开发指挥车车厢骨架全部采用铝合金骨架，纵横骨架梁之间通过钢制 连接块及L型连接板螺栓连接。以有限元分析理论为基础，针对2种配重方案，对新开发车型的全铝合金车厢骨 架强度进行计算，计算结果表明:原结构设计刚度不满足要求。提出相应的结构优化改进设计方案，刚度满足需 求。

关键词: 铝合金, 骨架, 强度, 刚度分析

Abstract: In order to reduce weight and improve assembly efficiency，a newly-developed command vehicle compartment frame is made up of aluminum with its vertical and horizontal frame beam connected through the block and L－shape flat steel． Based on finite element theory，calculation of strength was carried out in the newly－developed vehicle according to two counterweight plans． Results indicated that rigidity of the original structural design could not meet the requirements and structural optimization and improvement of design were put forward to make the rigidity meet the needs．

Key words: aluminum alloy, frame, strength, rigidity optimization
