Force Analysis and Optimization Selection of the Bottom Beam Assembly of a Fully Hydraulic Impact Reverse Circulation Drilling Machine
This article compares the cross-sectional parameters of different types of bottom beams for fully hydraulic impact reverse circulation drilling rigs,and analyzes the strength and bending stiffness of different types of beams.The results indicate that optimizing the selection can meet the demand for lightweight bottom beams when meeting the load requirements of the entire machine.Through this analysis,the problem of overall lightweight can be effectively solved.
