【正文】 5 Nms/rad 發(fā)動機安裝彈簧系數 16269 Nms/rad 發(fā)動機慣性矩 kg. 2m 輸入軸慣性矩 kg. 2m 輸入軸彈簧系數 4920Nm/rad 輸入軸阻尼系數 Nms/rad 輸出軸彈簧系數 16300Nm/rad 輸出軸 阻尼系數 Nms/rad 實心軸轉動慣量 kg. 2m 空心軸轉動慣量 kg. 2m 中間軸轉動慣量 kg. 2m 以升檔為例，雙離合變速器的輸出扭矩情況見圖 5。在扭矩階段里，由于檔位的瞬變，變速器的扭矩輸出值會降到最低值。 慣性階段會造成大多數扭矩的回升，并且在此階段有很多扭矩的極端情況發(fā)生。 圖 5 典型 DCT換擋過程輸出扭矩概略圖 汽車起步階段 汽車由靜止開始起步，控制離合器 1 使一檔齒輪嚙合。同樣的，對于一個比較慢的起步，同樣的扭矩就會緩慢下降，并且離合器接合的時間會增加。 12 升檔過程 這個實驗模擬了在開放性的油門環(huán)境中，由一檔到二檔的升檔過程。圖 9 描繪了即將接合與分離的離合器的相對角速度。 每一組雙離合器的曲線圖都與離合器接合和分離時的曲線存在不同點。這三種不同扭矩的比照具體見圖 11。在 Stateflow 的齒輪選擇器中，如果剎車信號占主要優(yōu)勢，就需要檢查一個附加的條件，那就是什么時候剎車信號檢測到變速器要開始降檔了 。 本文對離合器的接合時機以及離合器的壓力控制信號這些重要內容進行了 數值 分析，同時解釋了仿真模擬的相應情況。 【 參考文獻 】 [1] G.
