Active Damping of Railway Carbody Vibrations with Piezoelements

Abstract

This paper presents a methodology for the simulation and control of smart structures with piezoceramic patches by means of multibody dynamics. A theoretical background is mentioned adapting a modal multifield approach. Then a methodology for the control design is proposed. The methodology includes the optimisation of actuator placement, which is based on modal representation of the elasticity. The methodology is applied for simulation and control synthesis of an active damping for a railway carbody. The application example illustrates the implemented process chain. This procedure provides a complex development environment for the simulation, optimisation and control design of elastic structures with smart materials.
