Notice of Retraction: Numerical simulation and analysis for transient thermal field of a drum brake based on the test

Three-dimensional finite element model of a drum brake is built in this paper. According to test conditions of brake heat fade and other relevant national standards, using ANSYS Workbench, brake drum thermal field is simulated and studied. Through several simulation methods revised about initial conditions, to achieve fitting of the simulation curve and test curve. The boundary conditions for temperature field analysis and simulation methods of the brake drum are confirmed, and the effects of the process of braking speed, braking frequency and braking force etc. to brake drum thermal field are studied. To provide an important reference for the thermal performance analysis of brake at design stage.
