摘要
本文介绍了用坐标转换计算斗齿位置和特殊工作尺寸以及相应的三组液压缸长度的方法,建立了挖掘轨迹包络曲线的数学模型,提出了包络图面积的计算方法,并给出实例.
This paper introduces the calculating methods of bucketteeth position,specific operating sizes and respective lengths of 3 setsof hydraulic cylinders by coordinate transformation,establishes themathematical models of digging path enveloping curve and presents thecalculatinig method of the enveloping drawing area.In the meantime,example is given.
