摘要
对固结在转动刚体上柔性梁的动力学问题进行了研究.采用拉格朗日方程建立了三种不同情形的转动刚体上柔性悬臂梁系统的动力学方程.对系统耦合与非耦合方程进行了仿真,并通过仿真计算比较说明非耦合方程的局限性.
The dynamics of a cantilever beam attached to a rotating rigid body is presented. The governing equations for three different cases are derived from the Lagrange,s equations. The coupled and uncoupled equations of motion are simulated respectively. The limitations of the uncoupled equations are revealed by computation simulation and comparison.
