Abstract

A novel device that uses friction between one or more pairs of elastic conical rings to dissipate the energy from an impacting body is presented. The device consists of one moving and one stationary cylinders coupled to each other using two pairs of conical rings and a spring. The spring is used to restore the system to its original configuration after the impact. The dynamic response of the system to the impact forces during impact events is analysed numerically and experimentally. The effects of several governing parameters, such as the mass ratio between the cylinders, the duration of the transient response of the device, the magnitude of the rest zone of the moving element and the peak impact force are investigated. The proposed system is applicable in sequential impact scenarios, in which remarkable improvements were observed over traditional solid-rod impact absorbers. The present study may serve as a guide for the design of improved damping devices for impact applications. © 2014 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.
