一种全金属网面轮胎的设计、仿真与试验研究

为避免车辆轮胎因扎刺或弹片侵彻等引起的爆胎问题，设计一种非充气型全金属网面车轮结构。建立关于轮胎的垂向刚度预测、垂向振动的理论分析模型；结合三维建模软件Pro/E、有限元前处理软件ANSA和有限元仿真软件Abaqus建立轮胎仿真模型；制作与235/70 R16型号充气轮胎同尺寸的轮胎样机，开展轮胎静力学压板试验和车辆平顺性试验。仿真结果表明，该金属轮胎在各向力作用下不会产生塑性变形，满足轮胎使用的强度条件；通过垂向刚度试验，验证了仿真过程的准确性和轮胎较强的承载能力；平顺性试验表明，金属轮胎在减振性能上略差于充气轮胎，但具有更好的抓地特性。

DesignSimulation and Test Study of an All-metal Mesh Tire

A new non-inflatable all-metal tire structure is designed to prevent the tire burst due to puncture and shrapnel penetration. Theoretical models of vertical stiffness prediction and vertical vibration are established. A tire simulation model is built using 3D modelling software Pro/E, finite element preprocessing software ANSA and fimite element simulation software Abaqus. A metal tire prototype which has the same size as the pneumatic tire (235/70 R16) was made, and the plate loading test and vehicle ride comfort test were carried out. Simulated results show that the metal tire is not plastically deformed under the action of force in each direction, which meets the strength requirement. The accuracy of the simulation process and the strong bearing capacity of the tire are verified by the vertical stiffness test results. The ride comfort test results show that the metal tire is slightly worse than the pneumatic tire in vibration damping performance, but has better grip characteristics. Key
