複合形防振ゴムのばね定数

Formerly, the rubber vibration isolators of fundamental type have been discussed in various ways, but practically, those of compound type are often used, and there various types of the latter isolators. So the authors picked up the typical types which are generally used, and tried to calculate and arrange the formulae to get the stresses induced in rubber parts and their spring constants. In this study a special attention was paid to the shearing stress. Generally, the shearing stress does not distribute uniformly over the cross section, so the influence of this fact should be considered in such short machine parts as rubber vibration isolators. Then, we have to derive some correction in the calculation of shearing stress, Whenupon, putting the coefficient to correct this stress as β, the authors calculated β and found that it is the function of only the inclination of cross section of rubber for the load.
