| 摘 要： | 采用有限段方法建立柔性梁式的离散模型，基于Ｋａｎｅ方程的Ｈｕｓｔｏｎ方法建立柔性多体系统学方法，该方程计入了梁式构件的几何非线性变形的惯性影响，在求解过程中，引入了相对位移的模态变换以提高计算效率，通过典型实验验证了有限段方法可解决具有几何非线性变形的柔性梁式构件的多体系统的动力学问题。

| Abstract: | The dynamic equations of multibody systems with flexible members are developed by means of Huston's method based on Kane's equations. The finite segment method is adopted to established the models of the beam like members. The inertia effects of the nonlinear deforations of the beams are taken into account,and the mode transformation of relative displacements is introduced into the calculating process to increase the efficiency. A typical experimental result verifies that foregoing method can be used for dynamic analysis of multibody systems with the beams undergoing nonlinear deformmations |
