Characteristics of a Fix-End Torsion Spring Oscillatory Actuator with Molded Silicone Rubber

Abstract:

This paper introduced a novel actuator constructed by a flexible torsion spring with molded silicone rubber. The torsion spring is fixed at the ends to obtain the high rigidity and is molded by a silicone rubber material to achieve the high reliability. The actuator has the resonant frequency of f₀=59Hz on the scanning direction and f_β =239Hz on the longitude direction. The maximal stress is 0.168MPa compared to the yield strength of 4.3MPa and the predicted safety factor is 25.6.
