Abstract. The development and realisation of an active interface for decoupling two mechanical systems is presented. Thereby a method is introduced allowing the design of an active interface by means of rapid-prototyping on basis of the simulation of the adaptronical system.
The method includes the calculation of the dynamic behaviour of the mechanical structure with the help of FEM. The FE-model is reduced subsequently and embedded as a modal state-space-model in the MATLAB/ Simulink-environment. In the next step the actuators and sensors are integrated into the mechanical structure. Based on the resulting dynamical behaviour of the mechanical structure an adaptive control algorithm for the decoupling of structural vibrations is developed.
Simultaneously experimental tests are performed to confirm the simulations. First the experimental results are used to verify and to up-date the FE-model and the modal state-space model. In the following the hardware-in-the-loop-simulation performed with a Dspace-system is compared with the experimaental result. The result leads to a verified numerical model of the adaptronical system which allows the judgement and description for the performace of future, more complex adaptive mechanical structures.
