The response of a tilted dynamic vibration absorber system with a parametrically excited pendulum or with a dynamically resonated pendulum is numerically investigated. It is found that each dynamic vibration absorber is useful for suppressing vibration of the main system under some tilted angle, but not under all the tilted angle from 0 to 90 degree. And their vibration absorbing characteristics are dependent on the parameters of pendulum such as ratio of mass and damping ratio. In this paper, the vibration absorbing characteristic of the system is clarified, and the optimum parameters of each dynamic vibration absorber, which make the response of the main system minimum in some range close to the resonance frequency under tilted angles, are obtained. It is shown that the better results of suppressing vibration can be attained using optimum parameters.
