Abstract

A demonstrator representing a lightweight engine mounting for turboprop aircraft has been developed which allows for active suppression of disturbing vibrations. It consists of an advanced CFRP truss structure based upon high-load CFRP struts which enable an optimal integration of piezo-electric stack actuators. The dynamic behaviour of the truss structure was analyzed by a 3D-simulation and the optimal position of active struts was evaluated. The experimental results of static and dynamic tests showed very good agreement with the analytical predictions. First investigations of the active vibration suppression by means of a simple feedback controller exhibited an excellent functionality of the adaptive structure and a promising potential to future improvements.
