抄録

The mechanical properties of rubber vibration isolators depend on the amplitude, frequency, temperature, inclination and mean stress, and have remarkable shape effect. When designing, not only such properties but also the kinds of rubber, the conditions of vulcanization, the influences of blending and coating of different rubbers as to the characteristics of materials have to be considered. Furthermore, the deformation of rubber under usual stress is not infinitesimal. The author has continued calculations and experiments in view of the theory of viscoplasto-elasticity advanced by Prof. Sawaragi and strength of materials. And now it becomes possible to calculate the apparent modulus and spring constant by the successive approximation method. From such results a rational method to design rubber vibration isolators is contrived, considering terms above mentioned as much as possible. In this method using nomographs, design can be expedited with a high accuracy.
