【 摘 要 】

The objective assessment indexes of shuttle shift quality of wheel loader are investigated. The process of shuttle shift is divided into two stages. At the deceleration stage, a large jerk value is observed, and a maximum acceleration value is reached when the shuttle clutch is synchronized. At the acceleration stage, the jerk is too small to be an index of comfortableness. The maximum acceleration, vibration dose value (VDV) and jerk of deceleration stage show a good linear correlation, meaning that the three indexes have similar representative ability for comfortableness assessment. The total duration of shuttle shift is chosen as an index because it is directly related to working efficiency. The duration, in which the torque converter plays a dominant role, is more than 50% of the total duration of shuttle shift, indicating that the duration of shuttle shift is mainly determined by torque converter's characteristics. The overshoot distance is chosen as the index to represent the dimensional behaviour of the shuttle shift.
