All-metal vibration isolators are widely used in vibration isolation systems due to its high strength, long service life, considerable energy dissipation coefficient. The elastic-damping elements of these vibration isolators are made of pressed wire materials, such as MR (Russia) and Spring Cushion (Germany). The comparison of the load carrying capacity, energy and life-time, the dimensional, mass and amplitude-frequency characteristics of vibration isolators made from these two materials. It is established that the isolator made of MR material compared with the isolator made of Spring Cushion material with similar life-time has a greater load-bearing capacity (it is 3-4 times greater) and damping properties (it is 1.5-2 times greater). The vibration isolators made of MR material of VVM-70 and DKU-90 types compared with the vibration isolator made of Spring Cushion material produced by STOP-CHOC company provide lower (1.5-2 times lower, respectively) transfer and frequency ratios within the resonant mode of vibration, which leads to higher vibration isolation properties of vibration isolators produced of MR material.
