Finite Element Analysis of Assembly Body of Conical Pick

Abstract:

In order to improve the structure mechanics performance of assembly body of conical pick, the finite element method was taken to analyse assembly body of conical pick based on rock cutting theory, and the distortion law of stress and displacement of carbide tip, pick arbor and pick holder were obtained. The results show that the maximum stress appearing in pick carbide tip and its weld site is 371MPa, maximum stress of pick holder appearing in its weld site is 157MPa. Consequently, the quality of the weld should be ensured in processing and manufacturing or welding installation to reduce the performance of carbide tip and pick holder drop. The maximum displacement of assembly body of conical pick is 1.14mm, which has little influence on the structure mechanics performance of assembly body. The research results could provide some guidance for designing, manufacturing or welding the assembly body of conical pick.
