中文摘要:
      基于ABAQUS软件建立225/40R18跑气保用轮胎和普通轮胎的三维有限元模型，分析标准负荷下2种轮胎在静负荷和稳态侧偏工况下的力学性能。结果表明，静负荷工况下，高应变能密度主要集中在支撑胶、带束层和冠带层端部，且在缺气状态下表现更明显，跑气保用轮胎胎肩处的接地压力大于普通轮胎，且径向刚度高于普通轮胎，缺气状态下跑气保用轮胎胎侧变形小于普通轮胎，且胎肩接地压力集中程度高；稳态侧偏工况下，在标准充气压力和缺气状态下，随着侧偏角的增大，跑气保用轮胎的接地印痕从矩形变为梯形，普通轮胎的接地印痕从矩形变为三角形。
英文摘要:
      Based on ABAQUS software，the three dimensional FEA models of 225/40R18 run-flat tire and traditional tire were established and the mechanical properties of tires under standard load in static load condition and steady cornering condition were analyzed.The results showed that，in the static load condition，either with normal tire pressure or under inflated pressure，high strain energy density was mainly on self-supporting rubber， belt and cap ends，especially in under-inflation state.In addition，the contact pressure at tire shoulder and radial stiffness of the run-flat tire were higher than traditional tire.When tires were under inflated，the sidewall deformation of run-flat tire was smaller than traditional tire，and the concentration level of contact pressure in tire shoulder was much higher than traditional tire.When tires were under steady cornering condition，either with normal tire pressure or under inflated pressure，the footprint of run-flat tire changed from rectangular shape into trapezoid with the increase of side cornering angle，while the footprint of traditional tire changed from rectangle into triangle.
