This paper stated the application of parallel link mechanism in modern machine tools , set up the error analysis as to parallel link mechanism in the virtucal - axis machine tool , derived the double triangular error equations of parallel link mechanicsm in its horizontal posture , analyzed the linearity and non - singularity of the error equations , thus giving the normal splution to the horizontal posture error . the error distribution law is simulated as to the center line in the workplace , and the error distribution curves are drawn as well
该文对并联机构在现代机床上的应用作了论述，建立了虚拟轴机床并联机构的一种误差分析方法，应用坐标变换原理导出了双三角并联机构水平姿态时的误差方程组；分析了误差方程组的线性和非奇异性，给出了水平姿态时的位姿误差正解；对工作空间中心线的误差分布规律进行了仿真，绘制了其误差分布曲线。
