悬挂式挖坑机钻头螺旋面载荷分布规律初探

Regular Patterns of Loading Distribution of Auger Face for Mounted Hole Digger

在室内土槽实验的基础上，经数据采集和动载荷特性分析，运用数理统计理论，建立了多元线性正交回归分析模型，得出了挖坑机钻头螺旋面的载荷分布规律。

Based on the in-lab earth channel experiments and through data collec-tion and analysis of characteristics of dynamic loading ,the model of porality linear per-pendicular regression analysis is established using statistic theory thereby to obtain theregular patterns of loading distribution of auger face for hole digger.
