摘要
随着高速列车不断提速,车内声环境问题越发凸显,车窗是距离人耳最近的隔声元件,但目前鲜有针对新型车窗在高速列车运行环境下的隔声特性的研究。本文针对高速列车运行环境下不同参数的真空车窗玻璃进行隔声性能计算,并将其板件厚度、声桥长度和真空度属性对隔声性能的影响规律进行总结;以北京航空航天大学电致变色中心某型电致变色玻璃为例,对电致变色车窗玻璃进行隔声性能探讨,高速列车车窗玻璃选型与改进提供一定理论参考。
With speed increasing of high-speed trains,the problem of the acoustic environment inside the car has become more and more prominent.Car window is the sound insulation element which is closest to the human ears.However,researches of sound insulation characteristics of the new type windows in the operation environment of high speed trains are very few.In this paper,the sound insulation performance of vacuum window glass with different parameters under the operating environment of high-speed trains is calculated.The influences of glass thickness,sound bridge length and vacuum properties on the sound insulation performance of the windows are summarized.With the electrochromic glass supplied by Beijing University of Aeronautics and Astronautics as an example,its sound insulation performance is discussed.This study has provided some theoretical reference for the selection and improvement of car window glass for high speed trains.
