英文摘要：

Based on the technology of virtual prototype, the kinematical simulation of the feed component for straight hole surface finishing is studied. The basic concept of surface finishing, the component unit and its working principle are presented. The motion mechanism in the hole is analyzed. Based on the software SolidWorks, the three dimensional modeling is built and the virtual assembling of feed component is designed. The relationship between preloads of driving and supporting wheels, traction force versus the feed speed, angle velocity and motor torque have been obtained with the aid of ADAMS ／ View simulation software so as to prove the correctness of the theoretical analyses, thus providing a design basis for developing of the feed component in straight hole surface finishing.
