The Effects Of The Electromagnetic Induction Heat On The Temperature Field Of The Pin-ring Friction Pair

With the needs of technology development and industry progress,the application of the finite element is booming.Based on the physical theory of the electromagnetic field,the temperature fields of the pin-ring friction pair under different materials,linear velocities,stresses have been simulated,while be coupled with different frequency magnetic induction heats.The regularities and causes of the temperature distribution under different working conditions were analyzed by finite element analysis software ANSYS.The main results and conclusions of the analysis are drawn as follows:In the rotation process of pin-ring friction pair,the temperature value of the contact area shows a decreasing trend from contact surface to surrounding,and the temperature gradients are getting smaller and smaller;the temperature changes are related to the stress and linear velocity in the case of the same rotation angle.With increasing electromagnetic induction frequency,the maximum temperature value increases to a controllable temperature in a relatively short time under the introduction of magnetic field.The change of electric current frequency can control the temperature of friction pair.Under the same rotation angle and duration 0.2s,the temperature contours of pin-ring friction pair have been coupled with the input of temperature load.The increases of the maximum temperature value are related to linear speed,normal stress and coupling current frequency.
