| 摘 要： | 为获得考虑运动副间隙和杆长误差的平面连杆机构运动规律，采用复数矢量法，推导出运动误差计算公式，在此基础上建立了曲柄滑块机构运动精度可靠性分析模型，编制了相应的计算机软件，并计算出算例机构位置参数和输出运动误差的方差和可靠度。

| Abstract: | In order to obtain planar linkage kinematics law considering kinematic pair gap and structural error,the kinematic error formula is derived adopting the plural number vector law.The reliability analysis model of kinematic accuracy on slider crank mechanism is established based on the above formula.The relevant computer software is developed.Moreover,the position parameter and the variance and reliability degree of output movement error are worked out with a typical example. |
