摘要:

求解接头柔度是研究战术导弹弹体接头动特性的一个重要内容。现有的求解接头柔度的方法有:经验法;有限元法及拟合法等。本文提出在已知全弹固有特性的基础上采用摄动反设计迭代法来计算接头的柔度。

关键词: 接头柔度, 摄动反设计, 固有频率

Abstract:

By means of the experimenfal frequencies and modes of a tactical missile,the paper has applied the method of redesigning structural vibration modes by inverse perturbation to change the solution of the airframe joints'c.ompHances of a tactical missile into the simple form of linear equations.The example indicates that the method in a better one to obtain the compliances of air-frame joints.

Key words: compliances of joints, perfurbation redesign nafural frequency
