Research on the Compensation Method of Installation Errors in Guideway Straightness Measurement with PSD

Abstract:

Influence and Compensation Theory of Installation Errors in Guideway Straightness Measurement with PSD Is Analyzed. it Shows that Pincushion Distortion Affects PSD’s Accuracy, while Angle θ between Laser and Guideway, Error Angle Caused by Straightness Error and Angle β Generated when PSD Rotates about the Guideway Have Significant Influence on System Measurement Accuracy. PSD’s Pincushion Distortion Could Be Corrected and Installation State Can Be Determined by Measuring on Site and Calibrating with Laser Tracer. after Error Compensation, System Measurement Accuracy Is Greatly Improved.
