摘　　要：通过对汽车发动机缸孔珩磨头的运动轨迹的跟踪分析与重构,确定了珩磨头旋转速度、往复运动速度、下端停留时间、上下越程等主要运动参数的变化对珩磨头周向相位角的影响规律,重构磨粒运动轨迹轮廓,建立珩磨头运动参数与磨粒轨迹分布的映射关系模型。基于该模型,探索了控制珩磨轨迹分布的均匀性的看法,改善了缸孔珩磨精度。This paper ascertains the relationship between the honing head＇s rotation angle in circumferential direction of the cylinder bore and motion parameters through the analysis and reconstruction of the honing abrasive trajectory. The motion parameters include rotational speed, reciprocating velocity, bottom stroke delays time, and up and down overshoot length. Thus the distribution of the abrasive trajectory is obtained. Based on the research, the paper establishes the corresponding relationship between the honing head motion parameters and the distribution of abrasive trajectory. Finally through the control of abrasive trajectory distribution, it provides a method to improve the cylinder bore honing accuracy.
