柔性多体系统中的刚-柔耦合动力学

摘要

Based on Von-Karman's deformational theory,the coupled effects between the coupled deformation of middle plane of beams and large overall motions is presented.Using Jourdain's velocity principle and single direction recursive construction method,the general coupling dynamical equations are established.Two classical examples show the coupled effect between coupled deformation and large overall motion to flexible multi-body system consisted of beams.%基于Von-Karman变形理论，描述了弹性梁中面的耦合变形和大范围刚体运动之间的耦合，利用Jourdain速度变分原理和单向递推建模方法建立了由梁式构件组成的树状柔性多体系统的程式化耦合动力学方程，通过两个典型算例验证了这种耦合变形和大范围运动之间的耦合效应对作高速大范围刚体运动柔性多体系统动力学性质的影响。
