Abstract: Objective: In the context of urban rail transit development popularization and prevailing attention on train and environment vibration noise, in order to improve passengers' riding experience and comfort, it is necessary to conduct research on wheels noise reduction. Method: Based on wheelrail noise generation mechanism analysis, from the perspective of wheel design, the selection of lownoise wheel type is proposed. Through the analysis of damping ratio of damping ring wheels noise reduction and the research on noise reduction wheel materials and heat treatment processes, key technologies for the development of lownoise wheel can be mastered.Result & Conclusion: Research results show that based on ER9 material, the alloy composition of Cr and Al elements is optimized to meet the high plasticity and toughness requirements of noise reduction wheel, ensuring that ER9 material noise reduction wheels have good machining performance for the machining accuracy of damping grooves. At the same time, a matching new heat treatment process is developed to ensure the strength and hardness level of the wheel, thereby meeting the wheel service life requirement. The measurement of noise reduction performance of damping ring noisereduction wheel shows that in the free state of wheels, the noise reduction amount increases from single ring to double ring, but the impact of damping ring diameter on wheel vibration and sound radiation is not significant; under radial excitation, the noise reduction effect of double ring fully pretensioned damping wheel increases by 5.7 dB (A) compared to single ring fully pretensioned damping wheel; while under axial excitation, the noise reduction effect increases by 7.1 dB (A).
