MECHANICAL PROPERTIES OF RUBBER LIKE MATERIALS WITH CELLULAR HOLES USED FOR VIBRATION ISOLATORS

Abstract

With various types of the vibration isolation materials with cellular holes, the dy-namic complex elasticity, which is important in the field of the vibration problems but is rather difficult to obtain, was measured. While, the static chracteristics, hardness and static elasticity and viscosity, were also tested with the same materials, which can be obtained easily. Then, the interrelations of the both values were investigated and linear relations were observed between the static and dynamic values. Therefore, in design of the hand protectors or the handle covers for prevention of the harmful vib-ration, the dynamic complex elasticity of isolating materials can be estimated from their static values.
It was also found that effect of the sample's shape on the static elasticity did not exist in these materials with celluar holes.
