Designing Adaptronical Components for Compensation of Static and Quasi-Static Loads Available to Purchase

The increasing interest in active solutions for the compensation of static and quasi-static displacements at tooling machines, like mechatronics and adaptronics for example, must be looked at with regard to high dynamics and accuracy. Mechatronical systems for the compensation of displacements allow for high manufacturing accuracy and at the same time high machine dynamics. The high system costs make an application in industrial environments impossible. Besides mechatronics the area of adaptronics shows a high potential for cost reduction and system integration with a comparable functionality. This article describes the compensation for piezoelectric transducer stacks in the static and quasi-static range in particular. The piezoelectric transducers stand out for their excellent properties as actuators such as positioning accuracy and dynamics. The multifunctional properties of piezoelectric transducers allow for the spatial and functional integration of sensor and actuator for the realization of active components. Due to a limited time constant for the use of piezoelectric transducers as sensor, static loads must be transformed into a dynamic input signal for the transducer. The interdisciplinary design of the overall system is of vital importance. It is described and discussed by the example of the realization of an adaptronic strut with controllable elongation for parallel kinematics and an adaptronic hydrostatic pressure pocket unit for an intelligent hydrostatic leveling system.
