number of axles
解釋
軸數-
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 。 -
Furthermore, it discusses how to figure out these models mentioned above. with reference to the design of various automobiles, it primary defines the method to get key parameters in platform lorry general design, and creates mathematical model. it provides more reference to choose axis, driving axle, number of arrest axles, type of tire, pump, motor, lift hydrocylinder, maximum payload and sole weight reasonably
在參考各類汽車設計思想的基礎上，根據理論推導和經驗公式的計算，初步確定了平板車總體設計階段的主要技術參數的求解方法，建立了數學模型，為合理地選擇軸、驅動橋、制動橋個數，輪胎型號、泵、馬達、舉升油缸、平板車的最大載重量和自重的選擇等提供了依據。
