| 摘 要： | 为了改善拖拉机机械式自动变速器的换挡品质,减少驾驶员劳动强度,以换挡过程的冲击度作为换挡品质的主要衡量参数,设计了自动变速器的电-液执行机构,拖拉机自动变速器采用模糊控制的方法.试验结果表明,换挡过程中的冲击度最大值发生在离合器完全接合时刻,为4.76m/s3,小于我国的推荐值17.64m/s3,所设计的电-液执行机构及其模糊控制方法能够改善换挡品质,对于拖拉机自动换挡系统是可行的.

| 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 ... |
