中文摘要:
      对比不同流固耦合方法对轮胎滑水性能进行仿真分析的结果。在Workbench平台中分别采用单向、双向流固耦合方法,对轮胎滑水模型在相同工况下的胎面动水压力分布和轮胎变形进行计算,并将两种方法仿真预测的临界滑水速度与经验公式计算值进行比对。结果表明,相对于单向流固耦合方法,双向流固耦合方法计算的相同时刻的动水压力峰值和轮胎变形量峰值较低,压力分布更均匀,临界滑水速度精确度较高,表明双向流固耦合方法更适用于轮胎滑水性能仿真研究。
英文摘要:
      The simulation analysis results of different flow solid interaction(FSI)algorithm on tire hydroplaning performance were compared.The one-way and two-way FSI methods in the Workbench platform were used respectively to calculate the tread hydrodynamic pressure distribution and tire deformation under the same working conditions,and the critical hydroplaning speeds predicted by the two algorithms were compared with that obtained by the empirical formula.The results showed that,compared with the one-way FSI,the peak hydrodynamic pressure and the peak tire deformation at the same time calculated by the two-way FSI were lower,the pressure distribution was more uniform and the critical hydroplaning speed was more accurate,indicating that the two-way FSI algorithm was more suitable for the simulation study of tire hydroplaning performance.
