| Abstract: | Mechatronics has enabled “intelligent” machinery such as car antiskid braking systems to be created. Any new automotive development has to incorporate a large number of mechanical servo functions, and the range of functions and requirements in servo technology is growing apace. New actuator technologies, therefore, give fresh impetus to product development and accelerate progress. Piezoelectric actuators represent a new technology that offers a host of advantages. In combination with signal-processing electronics, the good mechanical and electrical integratability of piezoelectric actuators make these devices key elements in innovative, intelligent systems. This paper presents prototype applications. Particular attention is focused on powerful large-displacement piezoelectric actuators. The article also includes concrete characterization of piezoelectric actuator elements. To this end specific static and dynamic measurement methods were developed to characterize the elements under temperature and load influences. |
