| Abstract: | In order to study the partial-wear between rod and tubing in the mechanical production,the buckling deformation and the contact of tubing with inner rod and outer casing are considered,and the variable cross-section of structure and the annular clearance with the tubing and rod are assumed,the tubing post-buckling and the contact with casing and rod are simulated by using the nonlinear finite element method of large displacement with contact,and the initial displacement of tubing is obtained from the multi-... |
