Abstract

Using the finite element modal analysis technology, Noise, Vibration and Harshness (NVH) characteristics of car tires were analyzed. Through the establishment of finite element model of tire structure, the modal analysis and harmonic response analysis have been carried. From the the modal analysis results of tire structure, the wheel structure panel endured relatively strong local changes, the first three order modal natural frequency was the main causes of the pavement noise; the harmonic response analysis showed that the tire structure proned to resonance when the car tires was under 60 Hz frenquency. The tires forces were mainly concentrated in the tire lateral upper surface, tire deformation were mainly concentrated in the upper and lower part of tires, and easy to cause vibration and noise. Through the finite element study of the modal and harmonic response analysis of tire structure, we can better grasp the mechanism of vibration and noise, and guide the further design for the optimization tire to obtained the better NVH characteristics.
