Heat Transfer Simulation of Shrink Fitting of an Assembly | FEATool Multiphysics Tutorial
Heat Transfer Tutorial - Simulation of Shrink Fitting of an Assembly with the FEATool Multiphysics MATLAB toolbox https://www.featool.com
This example models shrink fitting of a two part assembly. A chilled tungsten rod is inserted into a slot in a heated steel frame. The rod can be fitted due to thermal expansion of the frame, and when the assembly reaches equilibrium temperature the two parts will be joined due to the ensuing pressure fit.
The model illustrates how to simulate the transient heat transfer process with two domains of different materials. The assembly is cooled due to convection through a surrounding medium, and the time when the maximum temperature has reached 70 C should be determined.
