摘要
提出了一种新型电子凸轮的概念,即利用特殊设计的压电陶瓷组合驱动器作为主动件,由有限元法确定输入的交流电压频率和输出的运动幅值之间的规律,通过控制组成周期性输入电压的分量的频率、幅度和初相位,驱动机构从动件输出的运动实现谐综合的特性,从而达到较高的运动输出精度。
A conception about a new type of dectronic cam is put forward in this paper. A special actuator made of piezoelectric ceramic combination is used as active piece. The relation between output movement amplitude vs frequency of alternative voltage is decided by a finite dement method. In order to get high output movement precision, the active piece of the mechanism is driven to realize harmonic synthesis movement characteristic through control of frequency, amplitude and initial phase of component periodical input voltage.
