摘要
对柔性多体系统动力学研究的若干阶段和研究现状进行回顾,对已有的刚柔耦合动力学建模方法进行总结.为了对已有的建模方法进行评价,提出了5项指标:科学性、通用性、识别性、兼容性和高效性,指出现有的建模方法尚无法满足工程实际应用的需要,应研究满足全部评价指标的刚柔耦合动力学建模方法.文中对今后柔性多体系统刚柔耦合动力学的几个研究方向进行展望,包括理论建模、计算方法和试验研究等方面.
A brief review about several phases and present status of flexible multi-body dynamics was given and the existing modeling methods of rigid-flexible coupling dynamics were summarized. Five indexes, including scientific index, general index, identifiable index, compatible index and efficient index, were proposed to evaluate the existed modeling methods. It shows that the existed modeling methods can not satisfy the actual needs of engineering application and new modeling method which satisfies all the evaluating indexes should be investigated. The research targets including modeling theory, computational methods and experiments were suggested for the rigid-flexible coupling dynamics of the flexible multi-body systems.
