    摘要:

    為了改善拖拉機機械式自動變速器的換擋品質(zhì),，減少駕駛員勞動強度,，以換擋過程的沖擊度作為換擋品質(zhì)的主要衡量參數(shù),，設(shè)計了自動變速器的電—液執(zhí)行機構(gòu)，拖拉機自動變速器采用模糊控制的方法,。試驗結(jié)果表明，換擋過程中的沖擊度最大值發(fā)生在離合器完全接合時刻,，為4.76m/s3,，小于我國的推薦值17.64m/s3，所設(shè)計的電—液執(zhí)行機構(gòu)及其模糊控制方法能夠改善換擋品質(zhì),，對于拖拉機自動換擋系統(tǒng)是可行的,。

    Abstract:

    A curve of the tractor automatic mechanism transmission (AMT) dynamic power shifting schedule was presented by conducting an experiment. Taking the degree of jerk during shifting as the primary control parameter of the shifting quality, the AMT control system was developed based on the electric hydraulic servo system. By analyzing the experience of a skilled driver, a fuzzy controller was designed, and the control algorithm of the tractor AMT dynamic power shifting schedule was established. The experiment results show that the faster the shifting is, the bigger the jerk is. The biggest jerk was 4.76m/s3 that happened at the clutch’s lock-up time, all of the jerk’s values were smaller than 17.64m/s3, which was the biggest jerk that people can endure. The results indicate that the fuzzy control method is feasible for the tractor AMT control, and can improve the quality of the tractor AMT shifting. 
