  1. Passages reserved for connecting the engine room to the outside ( e. g., the cooling fan outlet, the exhaust outlet, the ventilation outlet, etc. ) must be designed as muffling passages, whose insertion loss should also be equivalent to the sound insulation amount of the fender structure. only in this way can the environmental noise outside the engine room live up to the standard

    為機房與外界相通而預留的通道(如冷卻風扇出口、發動機排氣出口、機房通風換氣口等)必須設計成消聲通道,其插入損失也應與圍護結構的隔聲量相當,只有這樣做才可保證機房外的環境噪聲達標。
  2. The paper firstly combined the aerodynamic model, pollutant model, traffic model and the optimal operating fans selection model and then established the sample data gaining program to produce the optimal sample data ; secondly, the multi - layer forward neural network and the fuzzy control is combined within an equivalent structure, after the learning of sample data, the neural - fuzzy control system for the road tunnel longitudinal ventilation is produced ; thirdly, the optimal operating fans selection model is replaced by the fuzzy control model to make the tunnel ventilation simulation program, and then the control results under different traffic flow circumstances are evaluated in the matlab environment ; finally, the adaptive ability of the neural - fuzzy control system is discussed

    本文首先結合空氣動力學模型、污染模型、交通模型和最優風機開啟臺數選擇模型建立樣本數據獲取程序,利用該程序產生不同交通流下的最優樣本數據;然後,將多層前向神經網路與模糊控制進行結構等價型融合,通過學習最優樣本數據,建立公路隧道縱向通風神經模糊控制系統;之後,用此模糊控制模型替代最優風機開啟臺數選擇模型建立基於模糊控制的隧道通風模擬程序,在matlab下模擬模擬不同交通流下的隧道通風以測評控制效果;最後,對神經模糊控制系統的適應性進行了討論。
