| 標(biāo)題 |
| 鐵路橋梁聲屏障氣動(dòng)力初步分析(50 卷) |
| 英文標(biāo)題 |
| Elementary study on aerodynamics of acoustic barrier used in railway bridge |
| 摘要 |
| 應(yīng)用商業(yè)流體分析軟件FLUENT的動(dòng)網(wǎng)格技術(shù)對(duì)列車駛過(guò)聲屏障產(chǎn)生的氣動(dòng)力進(jìn)行了數(shù)值模擬，得到了聲屏障的氣動(dòng)力沿列車運(yùn)行方向和高度方向的變化規(guī)律。模擬結(jié)果與測(cè)試結(jié)果的一致性證實(shí)了模擬方法的有效性。 |
