摘要
利用ABAQUS软件建立计及复杂花纹的205/55R16型子午线轮胎3D有限元模型,通过接地试验验证了有限元模型的精度,并提取轮胎在滚动过程中单个节距花纹沟体积变化历程。结合Lighthill声学理论和FW-H方程,利用动网格技术将花纹沟体积变化历程作为流体计算边界条件,计算花纹泵浦噪声,并与试验结果取得了较好的一致性。在此基础上,分析了使用因素对轮胎泵浦噪声的影响,轮胎花纹泵浦噪声随载荷和速度的增加而增加,随着轮胎气压的增加而减小。泵浦噪声与滚动程中花纹沟体积变化率成正比,提出以单一节距花纹沟体积变化率作为泵浦噪声的评价指标,控制花纹沟变形可实现降噪,为设计低噪声轮胎提供了新思路。
A three-dimensional finite element model (FEA) of radial tire 205/55R16, considering the complex tread patterned tire's steady-state rolling, was established by ABAQUS software. The tire contact test was used to prove the reliability of FEA model, and the volume change behavior of single pitch pattern groove was achieved. Taking the changing course of single pitch pattern groove volume as boundary conditions, the Lighthill acoustic theory and FW-H model was used to analyze the pumping noise and the simulation result was consistent with the test. On this basis, the influence of use factors on pumping noise was considered, it increases with the growth of load and vehicle speed and decreases with tire pressure growth. The pumping noise is substantially proportional to the volume change rate of single pitch pattern groove, which could be considered as the evaluation index of tire pumping noise. Controlling the pattern deform is beneficial to reduce the pumping noise, which provide a new idea for low-noise tire.
