Study on Thermal Stresses of Cylinder Liner’s Fabrication Using FEM Analysis
In the process of casing casting, great temperature gradient leads to contraction deformation of cylinder liner, which influences the quality of products. The thermal stresses caused by temperature gradient were analyzed by finite element method. The numerical results show that high equivalent Von Mises stress(242MPa) occurs in the surface zone of the cylinder liner as Cooling down to room temperature within pipe die ,also there is plastic deformation in the internal and external surface zone. Reducing the cooling speed, decreasing the temperature gradient and aging can reduce the influence of thermal stresses.
