提出了一种求解在连续接触模型下含间隙机构运动微分方程的摄动方法.这种方法不是直接求解具有刚性(Stiff)很大的含间隙平面连杆机构的运动微分方程,而是通过求解无间隙标称机构来得到相应含间隙机构的动力响应,所得结果具有较好的精度,而计算量则大大减小.
A method to solve the perturbation of a moving differential equation with a gap mechanism under a continuous contact model is proposed. This method does not directly solve the differential equation of motion with a highly rigid Stiff mechanism with a gap planar linkage, but by solving Gap-free nominal mechanism to get the corresponding dynamic response with gap mechanism, the results obtained with better accuracy, and the amount of computation is greatly reduced.
