| 摘 要： | 分析了转动悬臂梁的自由振动问题,通过综合运用解析法和数值方法解决了悬臂梁振型函数过于复杂的问题.由于系统本身具有不能忽略的几何非线性因素,使所得到的系统的控制方程为一个强非线性方程.通过采用数值方法得到的系统的自由振动曲线表明,系统是稳定.

| Abstract: | Through analytical and numerical methodf,ree vibration of the cantilever beam with rotating motion is analyzed.For the influence of the geometric nonlinearityt,he governing equation is strongly nonlinear.The first-order approximate solution is obtained by introducing artificial parameter in the equation.Through numerical results show that this system is stable. |
