摘要

为研究隧道内地铁列车车内噪声特性，建立了隧道-车体有限元-边界元声学分析模型。基于地铁B型车车轨耦合模型和现场试验获取车体二系悬挂力激励和轮轨噪声激励，将激励施加到车体计算分析车内噪声，以广州轨道交通7号线列车噪声试验数据对仿真分析结果进行验证，并研究了结构声和空气声对车内噪声的影响规律。分析结果表明：车内各标准点声压级图变化趋势基本一致，峰值中心频率集中在630 Hz处，主要频段为200~1 600 Hz，车体转向架上方A声级比车体中心高约1.02~
2.35 dB（A）；结构声对车内噪声的主要影响频段在20~200 Hz，空气声对车内噪声的主要影响频段在200~5 000 Hz，其中500~5 000 Hz频段最为显著；60 km/h车速下，结构声荷载作用下车厢中心处A声级比空气声荷载作用下相同位置高约21 dB（A）。该研究成果可为降低列车车内噪声，改善车内声学环境提供理论依据。

Abstract

Here, to study characteristics of noise inside metro train in tunnel, the tunnel-car body finite element-acoustic boundary element analysis model was established. Based on the Metro B type car-rail coupled model and field tests, the car body secondary suspension force excitation and wheel-rail noise excitation were obtained. These excitations were exerted on the car body to simulate and analyze noise inside metro train. The simulation results were verified with the train noise test data of Guangzhou rail transit line 7, and effects of structural borne noise and airborne noise on noise inside metro train were studied. The analysis results showed that the change trend of sound pressure level diagram of each standard point in train is basically the same, the peak center frequency is concentrated at 630 Hz, the main frequency band is 200-1 600 Hz, the A sound level at the upper of car body bogie is about 1.02-2.35 dB (A) higher than that at car body center; the main influence frequency band of structure borne noise on car interior noise is 20-200 Hz, the main influence frequency band of airborne noise on car interior noise is 200-5 000 Hz, effects of the frequency band of 500-5 000 Hz are the most significant; when the train running speed is 60 km/h, the A sound level at car center under action of structural borne noise load is about 21 dB (A) higher than that at car center under action of airborne noise load; the study results can provide a theoretical basis for reducing car interior noise and improving car interior acoustic environment.
