【摘要】 如何连续、动态地改变交流电机转速为摩擦学试验机提供广泛的速度选择是摩擦学测试技术中的一个重要问题。针对摩擦学试验对速度的这种特殊要求,设计一种基于LabVIEW的变频器控制系统,通过PC机与变频器的串口通信协议控制变频器的运行。结果表明:该系统操作简单,响应速度快,能够连续、动态地改变电机转速,为环-块摩擦磨损试验机的试验系统提供了强大的技术支持。更多还原

【Abstract】 Determining how to change the rotate speed of the electromotor continuously and dynamically to provide various speeds for tribology testers is important in tribology testing.A system for serial communication between the PC and the transducer is designed based on LabVIEW to meet the special demand of the tester.The result shows that the system can be operated simply and respond rapidly to control the transducer accurately to change the rotate speed of the electromotor continuously and dynamically.It can provide powerful technology service equipped to the ring & block tribology tester.更多还原
