CLOSED-LOOP FINITE ELEMENT MODELING FOR ANALYSIS OF SMART STRUCTURES IN ANSYS ENVIRONMENT

摘要

It would be promising if one can simulate the closed-loop behavior of a smart system in an available FEM software such as "ANSYS". The ANSYS/Multiphysics software has the ability of coupling different physical domains and also modeling smart materials such as piezoelectric and piezoresistives, i.e. it has the capability of modeling smart structures. The dynamic modeling of the controlled structures is then realized by the ANSYS programming tool. This aspect highly facilitates the overall system behavior analysis and at the same time various control methods can be tested without noticing the time consuming structural analysis involved. In this research work, it is tried the mentioned idea to be implemented and some control strategies for the structural active damping to be examined.
