防振ゴムの形状効果について(第1報)

抄録

It is well known that the characteristics of rubber vibration isolators depend upon their shapes. So the authors obtained experimental equations which show the variations of their characteristics in relation to the shape factor S=(cross sectional area)/(free surface area). They previously proposed the successive approximation method already on a supposition that the variations of characteristics are chiefly caused by shape effect due to their deformations. Here the more accurate approximation method is presented on a supposition that the deformed shape is a sort of rotating parabolic body. And the radius of curvature of bonded part largely influences the moduli of rubber vibration isolators, but even in such cases this calculating method is applicable.
