  • Effects of loading characteristics on dynamic characteristics of a vibration isolator using air suspensions

抄録

<p>In this study we make clear the dynamic characteristics of a vibration isolator with two degrees of freedom, one degree of freedom in rotation around horizontal axis and one degree of freedom in vertical translation. The isolator consists of two pair of air suspensions with slit restrictions and reservoir tanks. Even if damping ratio of air suspension, which corresponds to the restriction coefficient of the slit restriction, is chosen in order to minimize resonance amplitude, the resonance amplitude increases in case of a mass of a supported object increasing. Moreover, even if the optimum damping ratio is chosen in order to minimize the resonance amplitude or the standard deviation of amplitude of the system, which corresponds to the response for random excitation, both value increase if offset of center of mass from a center of the pair of air suspensions increases. Thus, it is necessary to consider the mass of the supported object and the offset of center of mass of supported object in case of decreasing response of vibration isolator.</p>
