Abstract
Vibration insulators and elastic-damping supports made of MR (metal rubber) wire material are widely used. The wearing of this material under random load is researched. The material is considered as anisotropic continuous media. A middle stress in the material is taken as a load parameter. Changing of resonance frequency and vibration transfer coefficient at resonance during lifetime is researched as dependencies on middle stress and density of material. The equations describing these dependencies are obtained. Three types of wearing are described as dependencies on load and MR material parameters. The wire microphotographies after wearing are obtained. The mass lost during wearing as the dependency on stress and density of material is researched.
