作者在文[1]中提出了空间连杆机构运动误差分析的微小位移合成法,该法无须通过微分机构位移方程或约束方程求解误差灵敏度,就能直接分析多种原始误差引起的机构运动误差,且所求出的运动误差具有较简洁的表达式。本文将微小位移合成法应用于平面连杆机构,给出了相应的微小位移合成方程,对平面四杆(考虑轴线装配歪斜)、六杆和八杆机构进行了误差分析,给出了这些机构的输出误差的显示表达式,并对CHURCHILL剃齿机工作台机构进行了误差分析的数值计算。
In [1], this paper proposed a small displacement synthesis method for the motion error analysis of the spatial linkage mechanism. This method can directly analyze the mechanism motion error caused by a variety of original errors without solving the error sensitivity through the differential mechanism displacement equation or the constraint equation. , And the obtained motion error has a more concise expression. In this paper, the microdisplacement synthesis method is applied to the planar linkage mechanism, and the corresponding microdisplacement synthesis equation is given. The error analysis is carried out on the planar quadrupole (taking into account the axial assembly skew), the six-bar linkage and the eight-bar linkage mechanism. The output error of the expression, and CHURCHILL gear shaving machine workbench mechanism error analysis of the numerical calculation.
