Numerical Simulation on Local Induction Heating Process of Large Spur Gear
Local surface strengthening of large gear is one of the methods to improve its service life.A new type of induction heating device was used to locally heat the steel plate,and ANSYS APDL was used to simulate the process numerically to verify the reliability of the model.On this basis,the temperature field and stress field in the local induction heating process of large spur gear were simulated and solved,and the temperature uniformity and stress uniformity of the two heating schemes were compared and analyzed.The results show that the new induction heating device has high efficiency on dear induction heating,and the temperature uniformity of the two schemes at 5 s is 92.62%and 90.28%,respectively.The stress uniformity is 91.78%and 97.9%,respectively,and the variation trend of temperature uniformity and thermal stress uniformity is not synchronized.
