摘　　要：轮胎噪声和抓地性能间存在矛盾特性。为将猫爪不同步态下运动时展现出的良好静音、强抓地生物功能移植于轮胎中,实现协同提升轮胎噪声和抓地性能的目的,先借助VIC-2D平面非接触变形测试系统对猫不同步态下运动时爪垫的接地性态展开试验分析以明晰猫爪垫不同生物功能的实现机理;后利用猫爪生物功能实现机理指导轮胎花纹结构耦合仿生设计,并对轮胎耦合仿生设计前后的噪声和抓地性能进行仿真对比。结果表明,猫不同步态下运动时爪垫在接地几何、接地变形等接地性态上会产生适应性变化以满足实现不同生物功能时的力学需求;相较于原始轮胎,耦合仿生轮胎改善了胎面-路面间滚动接触时的径向激励力,增大了胎面接地区在X方向上的变形分布,实现了轮胎噪声和抓地性能的协同提升(噪声值降低1.16 dB,抓地力增大53.21 N)。相关研究对于提升我国绿色轮胎研发水平具有一定参考价值。There is a contradiction between tire noise and grip performance.In order to transplant the silent and grip biological function of cat’s paw pads in different gaits into the tire,and realized the purpose of improving tire noise and grip performance,it first carried out experimental analysis on the grounding performance of cat’s paw pads in different gaits with the help of vic-2d,so as to clarify the realization mechanism of different biological functions of cat’s paw pads;Then,the coupled bionic design of tire pattern structure is completed under the guidance of the biological function realization mechanism of cat’s paw pads,and the noise and grip performance before and after the bionic design of tire are compared.The results showed that when the cat’s paw pads moved under different gaits,it would produce adaptive changes in grounding properties,so as to meet the mechanical requirements of realizing different biological functional characteristics;Compared with the original tire,the bionic tire improved the radial excitation force during the rolling contact between the tread and the road surface,increased the deformation distribution in the X direction of the tread contact area,and realized the coordinated improvement of tire noise and grip performance(the noise value is reduced by 1.16 dB and the grip is increased by 53.21 N).The relevant research had a certain reference value for improving the R&D level of green tires in China.
