An interaction model between flexible structures and piezoelements useful in multi-body modelling

In this paper, a general procedure for the synthesis of a reduced dynamic model for the description of flexible structure coupled with piezoelectric sensors and actuators is shown. The authors built an interaction modelling procedure, useful in MSS (Mechanical System Simulation) software, using a theoretical and FEM (Finite Element Modelling) approach. By modifying and developing an existing modal synthesis method, which is used by most commercial software, a new mode component synthesis methodology was developed. This new procedure allows the simulation of any system containing flexible parts coupled with piezoelectric materials, in linear and non-linear behaviour, under any mechanical and electrical boundary condition both in the frequency and time domain. This opportunity is not permitted by both the theoretical-analytical and FEM approaches without the involvement of heavy, lengthy computational loads
