摘要
预应力和动平衡轮廓设计理论(PDEP)运用有限元法,以轮胎的预应力轮廓和动平衡轮廓为设计基准,充分考虑轮胎动态变形,通过改变在模型内的胎体轮廓来实现对带来层和胎圈施加张力,使其达到最佳动态平衡状态。通过优化负荷下轮胎的接地印痕和压力分布,达到相同条件下滚动半径增大,并控制带来层张力分布。采用PDEP理论设计胎体轮廓,可以提高轮胎的高速性能和乘坐舒适性。
PDEP(Prestressed and Dynamic Equilibrium Profile) concept for tire design hasbeen developed. According to this concept,the tire is designed using FEM on the basis ofprestressed and dynamic equilibrium profile. The dynamic deformation of the tire is fullyconsidered and the tyre profile in the mold is changed to apply the tension of the belt andbeads and thus to reach the optimum dynamic equilibrium. The footprint and pressuredistribution at ground contact area of tire under load are optimized to increase the rollingradius at the same conditions and control the tension distribution in the belt. Theperformance and comfortable ride of tire at high speed can be improved when the tire profileis designed based on the PDEP concept.
