摘      要：An improved analytical design to investigate the static stiffness of a convoluted air spring is developed and presented in this *** air spring provides improved ride comfort by achieving variable volume at various strokes of the *** analytical relation is derived to calculate the volume and the rate of change in the volume of the convoluted bellow with respect to various suspension *** expression is used in the equation to calculate the variable stiffness of the *** obtained analytical characteristics are validated with a detailed experiment to test the static vertical stiffness of the air *** convoluted air bellow is tested in an Avery spring-testing apparatus for various *** bellow is modeled in the ABAQUS environment to perform finite element analysis(FEA)to understand and visualize the deflection of the bellow at various elevated internal pressures and external *** proposed air spring model is a fiber-reinforced rubber bellow enclosed between two metal *** Mooney-Rivlin material model was used to model the hyperelastic rubber material for *** the results,it is observed that the experimental and analytical results match with a minor error of 7.54%.The derived relations and validations would provide design guidance at the developmental stage of air *** expressions would also play a major role in designing an effective active air suspension system by accurately calculating the required stiffness at various loads.
