Furthermore, this paper constructs a hub and spokes route network exampl, and analyses the application of the optimal scheduling model on this route network
並通過一個案例說明該種輪輻式航線網航班計劃優化模型的應用。The results show that the wayside noise increases 8db - 12db, if the train ' s velocity increase two times ; and increases 3 db, if the number of axles increase tow times ; and decreases 3db, if the distance far away from the track increase tow times damping loss factor increases, the wayside noise decreases ; coupling loss factor increase, the wayside noise increase
預測結果表明:列車通過時,在其他條件不變的情況下,列車速度增加一倍,輪軌輻射噪聲大約增加8db 12db ;列車軸數增加一倍,輪軌輻射噪聲大約增加3db ;預測點距軌道距離增加一倍,輪軌輻射噪聲大約降低3db 。The temperature and stress field of wagon wheel under the condition of long ramp way cycle braking in daqin line have been simulated by using fem and axial symmetry model results indicate that high stress area appears on the wheel web, and the strength of wheel meets the requirement of routine operation under current braking condition
摘要採用軸對稱模型和有限元方法,模擬了大秦線長大坡道循環制動條件下貨車車輪溫度和應力場,結果表明車輪高應力區出現在輻板上,現行制動條件下車輪強度滿足使用要求。Noise radiated by the rail vibration is considered to be the main portion of wheel / rail noise in the frequencies blew 3000hz
研究表明, 3000hz以下的輪軌噪聲中由鋼軌振動產生的輻射噪聲占輪軌噪聲的70 %以上。When i asked several other blind study subjects to draw a spinning wheel, one particularly clever rendition appeared repeatedly : several subjects showed the wheel ' s spokes as curved lines
當我要其他幾個盲人調查對象畫滾動的輪子時,一種特別聰明的再現反復方法出現了:有幾個調查對象用弧線表示輪輻。After lab test and onset installation test, it has been proved that this technology can effectively reduce the wheel - rail radiation noise
經過實驗室試驗和現場安裝試驗,證明該技術可有效降低輪軌輻射噪聲。分享友人
