Entwicklung piezobasierter Komponenten für den Maschinenbau

According to nonexisting calculation algorithms the impact of piezoceramic actuators in mechanical engineering is mostly not achieved. By the use of an electro-mechanical analogy for mapping the properties of the piezo actuator it is possible to establish calculation models that provide both, the essential electrical current of the amplifier and the detailed stiffness analysis. As example the author explains the actuator-sensor-unit for compensating the torsional load in the struts of a parallel kinematic machine. The calculation shows the compliance of the connection between actuator and the adjacent mechanical parts as the weak point of the current design
