Creation of large-size reflectors for spacecrafts is a topical issue for the space industry. The accuracy of the reflecting surface form and the structure weight are the main criteria for the reflector design. The accuracy of the reflecting surface form during a long-term operation is provided by adjustment when using piezoelectric motors in the reflector design. These motors have small weight-size parameters and can reach great torque values. The piezo motor is a distributed mechanical-acoustic oscillation system. Mechanical-acoustic oscillations are generated in the piezo motor by a PZT-stack and transmitted to an oscillator element, and then from the oscillator element to a load action element. At high frequencies, when dimensions of the oscillator are proportionate to the wavelength, the energy is transmitted by means of acoustic waves. In this case, mechanical waves practically are not involved in the energy transmission process. This thesis shows a method for selecting the material of a mechanical-acoustic oscillation system according to the efficiency of the acoustic energy transmission via a piezoelectric layered structure.

“…The mechanism was to make the piezoelectric stack actuator produce reverse displacement to resist the original deformation [17]. Azin et al proposed a piezoelectric stack actuator for the shape adjustment of antenna, which met the requirements of tensioner unit in the antenna shape regulation system [18,19]. However, the stroke of piezoelectric stack actuator is small because of the direct drive by the piezoelectric plates' deformation.…”

A novel bellows-type piezo-hydraulic actuator was proposed, manufactured and tested in this study. The influence of water on the piezoelectric vibrator was analyzed and the output performance of the actuator was tested. The results show that the maximum average velocities of the big bellows-type actuator (BBA) and the small bellows-type actuator (SBA) are 17.24 and 27.23 at 13.9 kHz. The maximum output forces are 0.163 N and 0.044 N, respectively. The self-locking forces of BBA and SBA are 0.059 N and 0.009 N. The characteristics of the actuator are simple structure, large displacement, and self-locking when power is off.
