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.
