Development of Shear Type Rubber Isolator

고무의 전단 탄성을 이용한 방진마운트 개발

Rubber isolator has many advantages compared with steel spring mount. Rubber has high internal damping and can be formed various shape depending on specific purpose. On the contrary, low modulus of elasticity of rubber results the instability of rubber isolator by buckling phenomenon. This paper presents the development of shear type rubber isolator for industrial application by using shear rigidity property of rubber. The static load-deflection characteristics of developed isolator has been analyzed by the FEM. Consequently, the static load testing and a measure of the effectiveness of a vibration isolator in terms of force transmissibility for developed isolator have been carried out.
