Finite Element Analysis of Low-Noise Wheel with Damping Control

The finite element analysis is conducted for the damping control of low-noise wheel,to which the technique of surface damping treatment has been applied.Computational formula for structure loss factor is deduced.By the use of the general software ANSYS,model analysis and harmonic response analysis are performed to four damping treatment design schemes.They are treatment on both sides of the web and under the rim,treatment on one side of the web and under the rim,treatment on both sides of the web and treatment on both sides under the rim.After contrasting the structure loss factors of the four damping design projects,the best project is presented.The research shows that the low-noise wheel has a good effect in reducing vibration and abating noise.In order to reach the better effect over a broad frequency range,laying the constrained damping layer on one side of the wheel surface is reasonable.
