摘要
为了在不影响轮胎寿命的前提下提升轮胎的滚动阻力性能,以某205/55R16型轿车子午线轮胎为研究对象,利用Abaqus和Fluent软件建立了轮胎自由滚动模型以及轮胎温度场模型,并通过温度测试和滚动阻力试验验证了仿真模型的可靠性。提出了应用满应力设计的轮胎轮廓优化设计理论,结合仿真模型,基于渐进优化算法针对轮胎外轮廓进行了优化。结果表明:应用满应力设计方法设计的轿车子午线轮胎滚动阻力显著下降;轮胎质量减轻;轮胎的应变能密度梯度模下降明显,轮胎寿命有所上升。证明了合理分配轮胎橡胶部件受力分布能够提升轮胎性能。
In order to improve the performance of rolling resistance and service life of Passenger Car Radial （PCR） tires, the PCR tire 205/55R16 is taken as the research object, and the finite element models of the tire free-rolling and the temperature field are established using Abaqus and Fluent software. The temperature and the rolling resistance are tested by a tire rolling r4esistance testing machine to validate the reliability of the simulation models. The contour theory is presented based on the full stress design theory. Combined with the simulation model, the outer contour of the radial tire is optimized using the evolutionary structural optimization, The results show that, compared with existing contour, the modified contour based on the full stress theory can be applied to reduce the weight of the tire, while decrease the rolling resistance. It is helpful to reduce the strain energy density gradient of the tier shoulder, which can improve the service life of the tier. In addition, the rational distribution of rubber parts can improve the performance of PCR tiers.
