摘要
经对挖坑机螺旋钻头的有限元计算分析，得出螺旋面的位移数据、应力分布规律及钻头易损部位。通过变换钻头结构参数，经模拟对比试验，找到影响强度的主要因素及参数的合理取值。计算值与实际相吻合。计算模型与方法切实可行，为挖坑机钻头的优化设计奠定了基础。
The displacement data of screw surface,the regular patterns of stressdistribution and the vulnerable damaging places of auger have been obtained through thefinite element calculation and analysis of screw auger of hole digger. Also, the factorsaffecting the strength and the rational scope of value counts of parameters for augerstructure are found out through the changes in structural parameters of auger and thesimulation contrast tests. The calculated values are in coincidence with the practicalones.As a result,the calculation model and the method are feasible,thus, laying a sol-id foundation for the optimal design of auger of hole digger.
