Design of Test Platform for Piezoelectric Stick-Slip Actuator

Piezoelectric stick-slip actuator (PSSA) is well-known by its simple configuration, minute step size, high resolution and theoretically unlimited displacement, and has been used in applications where high positioning resolution with large range of movement is required. This project designs an experimental test platform of stick-slip actuator which can be used to investigate the effects of temperature and pressure to the performance of end-effector. Embedded construction is applied for temperature sensor installation, which makes it easy to get more accurate temperature of the friction plate. A non-contact, electromagnet system is introduced in pressure adjustable mechanism. By changing the voltage direction and magnitude of coil, the pressure can be adjusted.
