挖坑理论
挖坑理论-
通过数据分析得出各影响因素与钻头动态力学参数间的数学关系，绘出关系曲线，作出曲线拟合方程，从而找出钻头动态力学参数达到最优时各影响因素值，为挖坑机设计提供理论依据。
Then the paper draws out the relation curve graph , and works out the close curve equation , thereby to find out the effects ' value when the drill 's dynamic mechanical parameters achieve the best condition , and provide theoretic basis for designing digging machine .
