摘　　要：本文对不同载荷下大变形柔性杆件的末端轨迹进行了分析,给出不同情况下柔性杆件伪刚体模型中各参数的确定方法。在此基础上,对一个大变形曲柄滑块机构分析了已知从动件规律,如何用伪刚体模型法求解主动件的驱动问题,其结果证明了伪刚体模型法在柔顺机构研究中的有效性。The paper firstly analyzed the tail end track of flexible rob under different loads. And the determining method about the parameters of pseudo-rigid-body model was discussed detailedly. Based on the discussion above, how to analyze the drive characteristic of a large-deflection crank-slider mechanism with pseudo-rigid-body model was presented when the deflection offollower was known. The results show the validity of the pseudo-rigid-body model in analyzing compliant mechanism.
