Vibration control of prallel structures connected with passive devices designed by GA

摘要

We propose design strategy of passive devices consisted of a spring and damper for controlling vibration of flexible structues arranged in parallel.A pair of two lumped mass for each flexible structrue is constructed in order to control the first two vibration modes,and connected by the passive devices between themselves.In this case,it is very difficult to design passive devices yb conventioonal theory using fixed point.In this paper,Genetic Algorithm is used to design passive devices.In this method,we determine a evaluate function in order to control vibration.then some passive elements are determined by GA.It is very easy to design the passive control system using this method.
