| Abstract: | Starting with the structure and working principle of the model 275 drilling pneumatic slip,restrictions and loads are added by the ANSYS soft,and the finite element analysis is carried out from the angle of drill pipes and slip body respectively to obtain the deformation map and stress nephogram.Thus the stress distribution conditions while clamping are determined and the unreasonable points are optimized and improved. |
