为解决二维轴对称模型或三维壳单元模型准确度不高和后处理空间不足的问题，本文使用Abaqus软件，利用三维实体单元模拟气囊囊壁，使用rebar单元模拟帘线层建立气囊隔振器模型，可有效提高仿真模型准确度，并建立气囊囊体模型对其等效平衡缠绕角进行仿真分析。开展不同载荷下气囊刚度特性试验，对比气囊气压-载荷特性、垂向静刚度等参数仿真计算结果和试验结果，表明仿真精度较好。本文的研究成果对下一步气囊隔振器疲劳寿命与可靠性研究具有一定指导意义。
To solve the problem of not-high accuracy and insufficient post processing space of the two-dimensional axisymmetric model or the 3D shell element model, the 3D entity element is used to simulate the air spring cyst wall by using Abaqus software. Using rebar element to simulate the cord layer, the model's accuracy was improved effectively and the air spring body model was built to analysis the equivalent balance wound angle. Carrying out the stiffness test of air spring under different loads and comparing simulation results and experiment results of pressure bearing capacity and vertical static stiffness, the simulation precision was preferable. The research results had a certain guiding significance to the study air spring's fatigue life.
