| 中文摘要: |
| 传统的柔性多体系统建模理论由于对柔性体的变形及其与大范围运动产生惯性力之间的耦合处理得过于简单，所以在分析存在高速大范围运动柔性多体系统的动力学性态时会得到完全错误的结论。本文将通过对作大范围运动弹性薄板的讨论来揭示产生这种错误的及探讨对传统性多体系统建模理论作出改进的对策 |
| 英文摘要: |
| The coupling between deformation of flexible body and the inertia forces caused by large overall motion is handled so simple that the complate erroneous results will be produced in dealing with the problems of high speed large overall motions by using traditional theory of flexible multibody systems. The cause of erroneous results are explained through analysis of a thin elastic plate in large overall motions and the coupling modeling method of flexible multibody systems is discussed in this paper. |
