| Abstract: | 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. |
