| 摘 要： | 针对含间隙机构运动精度低、可控性差的特点,利用连续接触模型对含间隙曲柄滑块机构进行动力学分析,得出含间隙机构的动力学方程组,通过龙格-库塔法求解该方程组,得到机构的运动特性图像,并从自由度理论的角度对机构可控性差的原因进行分析。结果表明:机构间隙大小和机构自由度的可变性是影响机构灵敏度的两大因素。

| Abstract: | Considering that a mechanism with clearance is of inferior precision and control, an analysis of its dynamic characteristics is done, based on a continuous model, to find out how the clearance makes influence on the sensitivity of a crank-slider mechanism. It can be shown that, the size of clearance and the changeability of freedom are the chief causes. |
