Various types of actuator, for example an air actuator, a linear moving actuator, a piezoelectric (PZT) actuator and a giant-magnetostrictive (GMS) actuator, have been used. In general, all actuators have both merits and demerits, so an optimal actuator should be selected based on the objective performance and the conditions of usage. We developed an active 6-DOF microvibration control system using GMS actuators. It has been speculated that the GMS actuator is suitable as a displacement actuator for an active microvibration control. The reasons for this are that it has better durability and reliability compared with a PZT actuator, and also its response to an input signal is much faster than an air actuator. However, the demerits of the GMS actuator come to light through practical application of the system. The displacement property tends to decrease with increase in the magnitude of forced axial load, and it cannot generate a sufficient displacement in a low frequency range.Read More
