Abstract
Section titled āAbstractāThe wear of diamond particles is an important factor that limits the working efficiency of diamond wire saws. In this paper, the physical model of diamond particle is established and the mechanical analysis is carried out. ANSYS finite element analysis software was applied to establishing unworn model and worn model for diamond particles. The cone angle of diamond particle, the protrusion height of diamond particle and the depth of the diamond particles press into the cutting face were analysed to study theirs effect on the shear stress extreme value of diamond particles in the process of cutting underwater pipeline. The results shown that the depth of the diamond particles press into the cutting surface and the cone angle of diamond particle have a great influence on the wear of the diamond particles, and the protrusion height of diamond particle is relatively small for the wear of the diamond particles.
