摘　　要：在酒井秀男和Frank非自然平衡轮廓设计理论的基础上,提出了新的充气轮胎非自然平衡轮廓积分方程。采用不同理论对11.00R20和385/65R22.5两种规格载重车子午线轮胎进行胎体轮廓设计。利用ABAQUS软件从轮胎磨损、滚动阻力和抓地力等方面,对采用3种不同轮廓理论设计的两种规格轮胎的性能进行对比分析,并与现行设计轮胎的性能进行对比。结果表明,Frank非平衡轮廓设计理论有利于提升轮胎磨损性能;酒井秀男非平衡轮廓设计理论有利于降低轮胎滚动阻力和提高轮胎抓地力;而新非自然平衡轮廓设计理论则可提升轮胎的整体性能,解决了轮胎不同性能间相互矛盾的难题。与现行设计轮胎相比,新非自然平衡轮廓理论设计的轮胎,在减小磨损、降低滚动阻力的同时提高了轮胎的抓地力。Based on Sakai Hideo＇s and Frank＇s non-natural equilibrium contour design theories,a set of integral equations for new non-natural equilibrium contour of inflated tire are proposed.The tire carcasses of two kinds of radial tires for trucks,11.00R20 and 385/65R22.5 are designed with three different theories of tire contour design.Their performances are then comparatively analyzed with ABAQUS from the aspects of tire wear,rolling resistance and ground grip capability,and also compared with the performance of tire by current design.The results show that Frank＇s non-natural equilibrium contour design theory is good at enhancing tire wear performance,Sakai＇s nonnatural equilibrium contour design theory is conducive to reducing the rolling resistance and improving the ground grip capability of tire,while the new non-natural equilibrium contour design theory proposed can enhance the overall performance of tire and resolve the contradiction between different performances of tire.Compared with tire of current design,the tire designed with new non-natural equilibrium contour design theory can have higher ground grip capability with lower rolling resistance and less wear.
