超声冲击装置输出功率控制

Power Control in Ultrasonic Impacting Equipment

在超声冲击处理过程中负载变化极其剧烈,为了保证超声冲击处理质量和效率,要求振动系统输出到负载的机械功率与负载大小成比例。文中介绍了超声冲击装置输出功率自动控制的方法,并给出了其输出功率自动调节电路。实验结果表明,在适当的工作条件下,系统能够监测负载阻抗变化,实时调整超声振动系统输出功率,满足振动系统的输出功率自动控制的要求。

The mechanical load may vary greatly during the ultrasonic impacting treatment process. In order to guarantee the treatment quality and efficiency, output power of vibration system must be in proportion to mechanical load. The method of output power control is reported in this paper. Based on this method, this paper introduces the circuit diagram of automatic output power adjustment. Experimental results show that this power-generating system can track the change in the mechanical load and automatically regulate the output power of the system, thus, meeting the desire of automatic output power adjustment.
