Research on the cord's wound angle in reversible sleeve air spring

在对某型膜式气囊帘线缠绕结构简化的基础上,运用几何分析和应力计算求得该型膜式气囊帘线的理论平衡缠绕角,并提出等效平衡缠绕角的概念。利用有限元仿真验证理论分析结果的正确性和等效平衡缠绕角的存在性。研究结果为膜式气囊设计与制造中的参数选取和工艺简化提供理论依据。

On the base of structure simplification of the RSA＇s（Reversible Sleeve Air Spring） cord, geometric analysis and force-equilibrium equations of microelements are used to get the theoretic equilibrium-wound angle of the RSA＇s cord, then present the concept of equivalent equilibrium-wound angle. The research results provide theoretic basis for the selecting of parameters and simplification of technologies in the RSA＇s design and manufacture.
