摘    要:利用ABAQUS软件建立了考虑声固耦合作用的光面胎滚动有限元模型,并对其进行滚动工况下Mises应力、接地性能以及振动模态等力学性能分析。从动力学分析结果中提取光面胎结构有限元模型的表面振动加速度,导入LMS Virtual.Lab Acoustics软件,采用声学边界元法分析光面胎滚动噪声;探讨了接地印痕、载荷、胎压和下沉量之间的关系,并对近场噪声仿真值与实验测量值进行了比较。研究结果表明:考虑声固耦合作用的光面胎Mises应力、接地压力、接地印痕呈对称分布,接触印痕、载荷、胎压随下沉量的增加而增大;考虑声固耦合的光面胎滚动噪声主要分布于50~375 Hz低频段,且内胎气体在滚动工况下产生了稳定声压(8 dB(A))。

关 键 词:光面胎  声固耦合  力学性能  滚动噪声

Abstract:A rolling finite element model of a smooth tire based on an acoustic-structural coupling model has been established by ABAQUS. The mechanical properties of Mises stress, grounding performance and vibration modal under load conditions have been analyzed. The surface vibration acceleration of the smooth tire was extracted from the results of dynamic analysis, and imported into the LMS Virtual.Lab Acoustics software. The acoustic BEM was used for the rolling noise analysis of the smooth tire. The relationship between footprint, load, tire pressure and vertical deflection is discussed, and the simulation results of near-field noise were compared with experimental test values. The results showed that the Mises stress, the ground pressure and the footprint of the smooth tire based on an acoustic-structural coupling model had a symmetrical distribution. The footprint, load and tire pressure all increased with increasing vertical deflection. The rolling noise of the smooth tire based on an acoustic-structural coupling model was mainly distributed in the low frequency range of 50-375 Hz, and a steady sound pressure of 8 dB (A) was generated by the inner tire gas.
