Jan 06, 2016· In addition, simulations and experiments showed that the natural frequency of the actuator is several KHz, which implies that the structural dynamic response is much faster then the electro-thermal dynamic response (the dynamic response is shown later in section 4). Thus, the mechanical inertia is considered to be quasi-static.
