Abstract:The dynamic characteristics of rubber damping ring were theoretically developed. The high elastic properties, frequency-related dynamic properties and friction-related dynamic properties were comprehensively considered, and the effect of shape factors was taken into account as well; a model of rubber damping ring with dynamic hysteresis characteristics was presented based on the bristle friction theory. Compared with the former model based on Coulomb friction theory, this model could describe the dependence of friction velocity and calculate the nonlinear characteristics of friction stress nearby the point of zero velocity, producing a lot of tiny wave features to the dynamic hysteresis loops. Experimental research on the measurement of radial dynamic hysteresis characteristics was conducted. Experimental results show that the actual dynamic hysteresis loops of rubber damping ring are approximate elliptic curves with many tiny waves instead of smooth ones. And the wave characteristics of the hysteresis loops are relatively obvious at higher exciting frequencies. The experimental research proves that the rules and trends of theoretical model based on the bristle friction theory and actual situation are consistent, and their characteristics are similar. © 2018, Editorial Department of Journal of Aerospace Power.
