| 摘 要： | 导弹弹体结构作为一非均匀质量和刚度的弹性体，计算其在随机激励下的动态响应是较困难的。文中给出了用李兹法求解导弹在随机激励下的动态响应的计算方法。与有限元法相比具有计算简单、节省时间、能在微机上实现编程计算等优点。可为确定弹上振动环境条件和室内模拟试验提供理论分析依据。

| Abstract: | Under random excitations, it is very difficult to calculate the dynamic response of missile which is an elastic body of non uniform mass and stiffness. A new approach using Litz method for the calculation of the dynamic response of missile under random excitations is presented. In comparison with the finite element method, the small amount of calculation, high efficiency and more convenience are the advantages of this method. It is possible to develop calculation program on microcomputers. This method can also provide bases of theory analysis for setting the vibration environment conditions of missile and indoor simulation tests. |
