Abstract

A new precise linear impact drive mechanism (IDM) was proposed. Differing from the traditional ones, the new IDM can run silently driven by sinusoidal electric voltage. But the actuating force was also inertial impact force generated by a set of asymmetrically clamped cantilever bimorphs. The dynamic characteristics had been experimentally studied on prototype of the IDM. The main results under 50 volt are listed below. The resolution is 27 nm, the maximum velocity 17 mm/s at 35 Hz. And, the maximum loading capacity is not less than 100 g when applied 100 V at 35 Hz.
