Slender shaft parts are very sensitive to thermal deformation

especially in the case of multi-position cladding

it is difficult to control its deformation. The effects of different cladding positions

cladding sequence and constraints on the deformation of the elongated shaft were compared. Finite element method and life-and-death element technology are adopted to analyze the relation of temperature field and deforming. The experiment data were compared with ANSYS simulation data to verify the correctness of ANSYS modeling

mesh division and the real validity of temperature field

stress field and deformation simulation. In the subsequent axial repair projects

the optimal cladding path with minimum deformation and stress concentration is firstly optimized by ANSYS numerical simulation

and then the cladding work is carried out. It improves the processing quality and reduces the cladding cost to a great extent.
