摘　　要：为了在恶劣行驶环境下提高轮式车辆轮胎的防爆胎防弹能力,基于金属螺旋弹簧的高强度与变形恢复特性,设计了一种弹簧轮胎。理论分析了轮胎各部件的结构参数,建立了轮胎的三维模型,运用有限元软件分析了轮胎的强度和刚度特性,进行了简易的轮式车辆试验。研究结果表明:轮胎结构有效地提高了车辆的安全防护能力,弹簧轮胎的力学分析理论模型和仿真模型准确,轮胎强度和刚度符合标准,同时试验为进一步分析和优化轮胎性能提供了依据。In order to improve the explosion prevention and bullet-proof ability of wheel vehicle tires in the serious environment, a spring tire was put forward based on the performance of high strength and deformation recover of metal coil spring. Structure parameters of each tire part were analyzed and three-dimension model for spring tire was established. The performance of strength and stiffness of spring tire were analyzed with finite elements software and simple wheel vehicle experiment was operated. Combining the analysis, it is validated that the structure efficiently improves safety protection ability and theoretical model and simulation model of spring tire are right. With getting performance criterion of spring tire strength and stiffness, deformation phenomenon of experiment provides theoretical guidance for analysis and optimization of spring tire performance
