【摘要】 本文用旋置理论导出了受空间力系作用的刚体旋量动态潜力学方程，其形式简洁，内函却十分丰富。作为一个特例用以推导平行齿轮曲柄滑块机构的动力学方程式，所得结果与传统的方法是完全一致的，且前者比后者在表达方式上夏简单、规范。更多还原

【Abstract】 In this paeer, the 3-D dynaMic equilibrium equation of the rigid bodysystem is derived by usins the screw theory. As an example, dynamic analysis of theparallel symmetric gear-crand-slidsr mechanianisms is deduced. In coninarison with themethods conventionally used, it is suporior in clarity and succinct.更多还原
