摘　　要：为验证炮塔结构设计的合理性,采用有限元方法分析炮塔的模态,并在此基础上运用模态叠加法分析炮塔在2种不同口径火炮射击状态下的动态响应,得到了炮塔的应力和位移随时间变化情况,验证了炮塔结构总设计的合理性,同时发现炮塔局部刚度存在缺陷。使用动力学分析方法不仅简化了验证炮塔结构的工作过程,还为该型炮塔的后期优化改进提供数值参考。In order to verify that the turret structure design is reasonable, turret mode was analyzed by u- sing finite element method, and the dynamic response of two different caliber artillery firing state was ana- lyzed by the use of modal superposition method based on the above analysis and got the changes of stress and displacement of the turret over time and verified the reasonableness of the overall design of the turret structure, and also found the disadvantages of the turret local stiffness flawed. Kinetic analysis used in the paper not only simplifies the process of verification of the turret structure, later also provides optimized and improved numerical reference for the turret.
