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.
