摘要
为了提高轮胎的防刺破、防爆胎和安全防弹性能,减轻重量,提出一种用于某型轮式特种车辆的无气轮胎,探索出一种新的轮胎设计方法.通过力学分析,建立了轮胎的结构模型,并利用有限元分析软件ANSYS对轮胎进行与地面的非线性大变形接触分析,获得车辆静态承载时车轮的受力与变形关系及应力分布情况,得到一些重要的设计参数,从而可以合理选材,改善胎体结构,优化设计方案.通过变形和接触力的关系得到轮胎的径向刚度曲线,为下一步的仿真分析提供重要的刚度参数.
To improve the tire performance of puncture-proof, explosion prevention, safety and bullet-proof, and weight decrease, a kind of airless tire used for military vehicle was put forward. A new type of tire design method was figured out. Through mechanism analysis, tire structure model was established. By utilizing ANSYS, a static nonlinear large deformation contract analysis between the tire and ground was carried out. The relationship between force and deformation and stress distribution of vehicle under static load was obtained, and meantime some crucial design parameters were gained too, through which, designer can reasonably select material, improve the tire structure and finally optimize the design scheme. The tire radial stiffness curve gained from the relationship between deformation and stress provides principal stiffness parameters for further simulation analysis.
