ROTARY PIEZOELECTRIC ACTUATOR COMPERAISE HELICAL CONVERSION MECHANISM

摘要

In this article we shall present a new concept of a rotary actuator. The actuator smartlyrnconverts a linear displacement of a piezoelectric stack into an angular movement. Thernactuator utilizes an output member and a helical coupling mechanism in a screw likernconfiguration. We will demonstrate a prototype mechanism employing threerncommercialized piezostacks. The capability of the actuator to operate under differentrndriving piezoelectric stacks configurations is demonstrated.
