摘　　要：通过噪声仿真软件VA one建立了电力机车司机室侧窗玻璃的统计能量仿真模型,对比分析了不同厚度的单层玻璃、不同中间空气层厚度的双层中空玻璃以及夹层玻璃的隔声量,并与试验结果相对比。仿真结果表明:夹层玻璃的隔声效果较好。Side-window glass SEA simulation model of electric locomotive cab was built with the noise simulation software VA one,and sound insulation of different-thickness single-layer glass,different-thickness intermediate-air layer hollow glass and laminated glass were analyzed by simulation and test.The simulation results showed that the laminated glass had the best sound insulation effect.
