摘　　要：为进一步提高工业CT系统多轴同步运动精度和CT扫描速度,采用基于SIMOTION运动控制系统虚拟主轴的控制策略,实现了DR(数字化辐射成像)扫描同步运动控制以及螺旋CT扫描三轴精确同步运动控制,通过调试试验及对工件的实际检测,证明其具有较高的控制精度和较小的跟随误差,能够满足工业CT的同步运动控制需求,并能保证获得高质量的DR和CT图像。In order to improve the precision of multi axis synchronous motion and CT scanning speed of the industrial CT system. The control strategy of virtual mainshaft is presented by using the SIMOTION control system, which realizes synchronous motion control of the DR(digital radiation imaging) scanning and three-axis synchronous motion control of spiral CT scanning. Higher control precision and smaller following error are verified in commissioning test and actual detection, which meets the needs of the synchronous motion control of the industrial CT and obtains high-quality CT scanning images and DR scanning images.
