摘要
针对目前工业CT扫描方式多、速度快,对运动位置与数据采集同步控制精度要求高的特点,提出了一种用高精度多轴数控系统来实现工业CT运动控制的技术,研究了二代、三代CT扫描运动的控制方法,实现了扫描参数的灵活设置与网络控制。通过对实际的二、三代扫描过程的仿真,旋转轴的控制精度达到0.001°,直线轴的控制精度达到0.002mm。实际测试表明,该控制技术能满足CT扫描过程中的多轴联动以及对数据采集同步控制的要求,具有较高的控制精度和较好的实时性。
According to the more scanning methods and the higher speed of industrial CT,the higher precision of the motion location and the data collection sync-control is required at present,a new motion control technology was proposed,which was established based on the universal CNC system with high precision of multi-axis control.Aiming at the second and the third generation of CT scanning motion,a control method was researched, and achieved the demands of the changeable parameters and network control.Through the simulation of the second and the third generation of CT scanning motion process,the control precision of the rotation axis reached 0.001°and the linear axis reached 0.002 mm.Practical tests showed this system can meet the requirements of the multi-axis motion integration and the sync signal control,it also have advantages in the control precision and the performance.
