Thermal Stress Simulation of Cooling Tube with Grid Plate Using Indirect Finite Element Method

Abstract:

Indirect finite element method was used to analyze the thermal - structural coupled field of cooling tube with grid plate, and the process of finite element modeling, loading and solution were given. Cooling grid tube deformation shape and node radial deformation curve were obtained by finite element analysis and the deformation increases gradually from pipeline inner wall to the outer wall, so the nonlinear performance is significantly. Deformation of grid plate increases linearly, and the maximum and minimum deformation are respectively for 0.32mm and 0.22mm. Diameter, axial and hoop stress distribution of cooling gate can be obtained, and the results show that heat transfer result in structure internal stress, radial stress is the state of compression at the place of cooling grid and pipeline Interchange, the axial stress is the state of compression in the middle of a cooling grid, the hoop stress is pressure at the wall of pipeline and tension at grid plate.
