Abstract

Cord’s theoretic equilibrium winding angle of an air spring capsule is too complicate to guide capsule cord’s laying in practical production. To solve this problem, the basic theory of air spring, the capsule cord’s equilibrium winding angle theory and the cord’s equivalent equilibrium winding angle theory were presented and studied here. The finite element analysis method was used to verify the results of the theoretical study. An air spring prototype made using the cord’s equivalent equilibrium winding angle theory was tested to get its load-bearing performance and stiffness characteristics. The test results showed that the prototype’s main parameters measured in tests agree well with the theoretical calculation ones, the correctness and feasibility of the cord’s equivalent equilibrium winding angle theory are verified; the cord’s equivalent equilibrium winding angle theory provides a theoretic basis for air spring’ design and production.

Key words： air spring capsule equivalent equilibrium winding angle stiffness characteristics
