基于流固耦合的轮胎花纹滑水性能研究
Research on the hydroplaning performance of tire tread groove based on fluid-structure coupling
摘要
Abstract
In this paper,the 205/55 R16 tire is used as the research object.Based on the Abaqus CEL fluid-structure coupling method,the finite element model of tire hydroplaning is built.The tire vertical stiffness generated from the simulation is compared with the experimental data.While validating the reliability of the tire model,the optimized Eulerian domain helps better capture and analyze the water flow characteristics during tire hydroplaning.The hydroplaning critical velocity generated by NASA empirical equations is employed to verify the reliability of the tire hydroplaning model.The impacts of different inflation pressure and water film thickness on the tire hydroplaning performance are analyzed.The tire tread structure is optimized by introducing a V-shaped transverse tread pattern and adding an F1 Nose structure.The validity of the optimized tread groove sub-model is verified,and then the hydroplaning critical velocity and water flow pressure of the tire before and after the optimization are compared.Results show our optimized method effectively improves tires'hydroplaning performances.关键词
