Finite Element Method Simulation of Induction Heating for A Large Marine Crankshaft

摘要

Shrink fit is an important method used to connect mechanical parts but less studied by three-dimensional finite element method. Based on the theories of induction heating and thermal conductivity, we established a three-dimensional FEM. The model included the induction coil, crank throw and air. The pattern of temperature field distribution during the period of induction heating were numerically simulated with software ANSYS. The simulation showed that, crank throw can obtain a uniform temperature field around the hole after induction heating. As a result, the crankshaft reaches a high-quality shrinkage fitting, manifesting the feasibility of the application of induction heating to the crankshaft shrinkage fitting.
