摘　　要：滚动噪声是高铁噪声的主要组成部分,为了探究铁路钢轨振动与滚动噪声间的相互关系,本文基于动力学与声波动理论建立车辆-轨道振动噪声联合分析模型。以轮轨联合粗糙度为纽带,分别研究钢轨振动与轮轨联合粗糙度以及滚动噪声与轮轨联合粗糙度的相关性,明确了钢轨振动与轮轨滚动噪声之间的传递关系,提出基于钢轨振动的滚动噪声预测方法。最后,以现场实测钢轨加速度和滚动噪声声压数据证明该预测方法的有效性。Rolling noise is a significant component of high-speed rail noise.This paper establishes a joint analysis model of vehicle-track vibration noise based on dynamics and acoustic wave theory to investigate the relationship between rail vibration and rolling noise in high-speed railways.By using the vehicle-track combined roughness as a connection,the correlation between rail vibration and vehicle-track combined roughness and between rolling noise and vehicle-track combined roughness is analyzed.This study elucidates the transmission relationship between rail vibration and vehicletrack rolling noise,proposes a rolling noise prediction method based on rail vibration,and validates the effectiveness of this prediction method through field measurements of rail acceleration and rolling noise sound pressure data.
