A survey of semi-active particle damping technology
Abstract:Basic concept, damping mechanism, application and studying status of particle damping technology and semi-active control technology were introduced, on which the research status of control algorithm was emphasized. Based on these two technologies, a new concept of semi-active particle damping technology was proposed, and a systematically investigation was presented, A new gear type semi-active particle damping device was developed accordingly, its working principle and control algorithm were explored. The numerical results show that this semi-active particle damping technology can greatly improve the vibration control effects, compared with passive control technology, indicating a potential promising application in engineering projects. Finally, the difficulties and deficiencies in the present studies were indicated, and some suggestions were provided.
Keywords: semi-active control particle damper impact damper vibration control
