摘　　要：与常规轨道交通相比,悬挂式空轨列车在车辆结构上有较大差异,在整车噪声方面表现出独特性,因此具有重要的研究价值。文章基于“源-路径-接收者”模式,分析了空轨列车振动噪声特性,并采用低噪声方案对车辆噪声指标加以控制,基于统计能量法(SEA)建立了空轨列车整车噪声仿真预测模型,通过噪声线路试验加以验证,结果显示二者具有高度的一致性。空轨列车在噪声控制方面相比常规轨道交通车辆具有显著优势,能更好地满足噪声标准并确保稳定运行。Compared with conventional rail transit vehicles,suspended monorail trains(sky trains)have great differences in vehicle structure,which contribute to their unique noise characteristics and underscore the value of researching this mode of transportation.In this study,the vibration noise characteristics of sky trains were explored,based on the source-path-receiver mode,and a low-noise scheme was designed to control vehicle noise indexes.Additionally,a simulation and prediction model for vehicle noise was established by utilizing the statistical energy approach(SEA).Furthermore,verification was conducted through noise path experiments,and the results showed a high degree of consistency with the simulations.Sky trains offer significant advantages over conventional rail transit vehicles in terms of noise control,highlighting their ability to better meet noise standards and ensure stable operation.
