Abstract: MR material (Metal Rubber) is manufactured by cold pressing of randomly placed wire spiral made of stainless steel. It has high strength, large energy dissipation coefficient, large working ability in aggressive environment, under high and low temperature. Vibration insulators with elastic-damping elements made of MR material are used widely. A research of life-time of vibration insulators made of MR material under random load is presented in this study. Dependencies of vibration insulator life-time on random load stress are obtained for different relative density, wire diameter, preliminary static deformation of MR material. Different types of MR material wearing are considered. Results of the present research are necessary for design of vibration protection systems with vibration insulators made of MR material.
