Advancement of non-pneumatic wheels and mechanical characteristics

介绍了轮胎安全技术的基本概念,对非充气车轮的基本内涵、结构组成以及主要分类作了详细阐述.列举了几种非充气车轮的代表产品,如Tweel车轮、蜂窝车轮以及机械弹性车轮等,并分析了非充气车轮的技术现状.从垂向力学特性、纵向力学特性、侧向力学特性、接地特性、振动特性以及力学特性影响因素等方面,综述了国内外非充气车轮力学特性的研究现状,并进一步分析了目前非充气车轮存在的主要优缺点.指出了在当前非充气车轮研究中应着重解决的技术问题,并对非充气车轮今后的发展趋势作了展望.

The basic concept of tire safety technology was briefly introduced,and the basic connotation,the structure and main categories of non-pneumatic wheels were described in detail. Several kinds of representative products of non-pneumatic wheels were enumerated with Tweel wheel,honeycomb wheel and mechanical elastic wheel,and the current technical status of non-pneumatic wheels was analyzed.Based on the vertical mechanical properties, the longitudinal mechanical properties, the lateral mechanical characteristics and the grounding and mechanics characteristic factors,the research status at home and abroad of mechanical properties of non-pneumatic wheels was reviewed, and the main advantages and disadvantages of non-pneumatic wheels were analyzed. The technical problems of nonpneumatic wheels in current research were pointed out,and the future development trend was predicted.
