The response of a tilted dynamic vibration absorber system with a pendulum under excitation is numerically investigated. Ratio of natural frequency of the pendulum to main system and damping coefficient of the pendulum are considered as main parameters. It is found that the vibration suppression effects can be obtained at wide range of the ratio of natural frequency of the pendulum to main system, and they are changed with the ratio and the tilted angles. However, the optimum vibration suppression effects can be obtained only at the parametrically excited pendulum or the dynamically resonated pendulum. Based on the analysis, the mechanism of the vibration suppression characteristic changed with the damping coefficient of the pendulum is clarified, and the method how to use a pendulum type dynamic vibration absorber to improve the vibration suppression characteristic of a tilted vibration system is suggested.
