抄録

In this report we treated the stiffness of bellows type air springs, and obtained the following [numerical formula] where As, ps and Vs : effective load area, pressure and volume of air spring at normal state, respectively. Va : volume of air chamber. pa : pressure of atmosphere. m : polytropic index. δ : elongation of air spring bellows par unit pressure in air spring. α, β, γ, and ζ : coefficients which depend on the shape of air spring bellows. and then, we calculated the values of α, β, γ, and ζ of tyre type of bellows. The results applied to air springs for railway cars and models of air springs, show close agreements with experiments.
