为进一步研究子午线轮胎胎面在300 Hz以上发生的横向弯曲振动特性,本研究参照被广泛使用的轮胎模态命名约定,通过建立205/55 R16子午线轮胎有限元模型,对胎面在0~500 Hz上的面内振动、面外振动和横向弯曲振动进行计算,获得对应阶数下的固有频率及模态振型。通过锤击实验对对象轮胎进行模态分析,获得0~500 Hz胎面振动模态,有限元模型的准确性得到验证。此外还通过对有限元模型施加旋转角速度,讨论轮胎频率分裂现象,并进一步得到转速与固有频率之间的关系。工作为研究轮胎在各个频段的振动特性和诊断车辆的NVH(Noise,Vibration,and Harshness)故障提供一种可供借鉴的思路和方法。
Numerical and Experimental Investigation of Transverse Bending Vibration Modes of Radial Tires
In order to study the transverse bending structural vibration characteristics of radial tire tread above 300 Hz,a finite element model for 205/55 R16 radial tire was established based on the widely used modal naming convention.The natural frequencies and modal shapes of in-plane,out-of-plane and transverse bending vibrations of tire tread in 0-500 Hz range were obtained.The simulation results of modals of the finite element model were verified by hammering test.In addi-tion,the phenomenon of tire frequency splitting of rotating tires was discussed by applying rotational speed to the finite ele-ment model,and the relationship between rotational speed and natural frequencies was analyzed.This investigation provides a referable methodology for studying the vibration behavior of tires in various frequency bands and diagnosing noise,vibra-tion,and harshness (NVH) faults of vehicles.
