弹性平面连杆机构振动响应的瞬时迁移子结构方法

本文将机构的运动周期离散化,在每个时间的分点上视机构为瞬时结构,利用逐步积分法及迁移子结构方法,将单元的控制微分方程转化为单元左右节点状态向量的迁移方程。文中详细叙述了该方法的基本思想,推导了有关公式,并用实例与前人的实验结果作比较,证明本方法简便、正确。

Method of Instantaneous Transfer Substructure on Vibrati Response of Planar Mechanisms with Elastic Links

The moving periods of mechanism are divided into n points, at each divided point, mechanisms are assumed to be instantaneous Structure. The governing differential equations of substructures (elements)are converted into transfer equations on the left and right nodal state vector by Step-by-step numerical integration algorithms and transfer substructure method, In this paper, the basic idea of this method is presented in detail, the calculating formulas is derived, The methos is proved to be simple and correct by Comparing with previously published experimental results.
