摘要
将大型旋转火箭的发射问题模化为变刚度柔性转子在轴力和横力作用下的空间约束时变系统，建立纵、横振动耦合的偏微分方程组，应用有限元广义变分法，给出发射过程中的动态响应和参数特性的数值解。
The launching problem of a large sized spinning rocket is considered.It can be modeled as a spatially bound system for a varying stiffness flexible rotor under constant thrust.Coupled partial differential equations of longitudinal and transverse vi-brations are established.Numerical solution if given for the dynamic response and pa-rameters behavior during launching applying the method of finite elements and general- ized calculus of variation.
