A two-step process is implemented to fully understand how a heat press machine works since ANSYS Fluent and Mechanical coupling are used for analysis. At first, ANSYS Fluent is used to solve fluid flow and energy equations. This step is all about describing heat distribution in the system, showing hot spots and places where the heating isn’t even. The temperature data is then brought into ANSYS Mechanical for structure analysis once the thermal profile has been set. Now, attention is on how the temperature changes affect the parts of the machine. The structural modelling figures out the thermal expansion, checks for stresses and strains, and looks at how the machine’s parts might change shape. Notably, the study is conducted based on a real industrial heat press machine.

Simulation Process
Having the heat press machine designed using Design Modeler, a 5582908-cell grid produced, concentrating on pipe`s wall. Regarding conductive heat transfer between pipes and steel plates, the heated hydraulic oil can emit heat. It is a one-way Fluid-Solid Interaction (FSI) simulation. More importantly, the structural steel properties are highly dependent on temperature. Consequently, the Young`s Modulus and Poisson`s Ratio are defined as a function of temperature. Here are the correlations:

Post-processing
As you can see from the simulation results, there is a clear temperature gradient across the heat press machine. This uneven heating, running from about 127°C to 187°C, suggests that it might be challenging to apply the same amount of pressure and heat to the whole surface. Furthermore, the structural analysis shows a substantial amount of total deformation, with the largest displacement of 1.7486 mm happening at the upper plate’s edges, as shown by the red areas in the deformation plot. This pattern of warping shows that the heat press may not be under the same amount of pressure all the time, which could change how consistent the results are across the surface of the machine. Given the stress tensor, the 129.51 MPa shear stress is strongest in certain places, mostly around the mechanical parts and the edges of the press plates. Based on the way the stress is distributed, these areas may wear down or even break over time, especially if they are loaded and unloaded many times with heat and force. Most of the structure, which is shown in dark blue, doesn’t experience much shear stress. This means that the design does a good job of spreading out the load, but the high-stress areas should be optimized to make the machine last longer and work better.
We pride ourselves on presenting unique products at CFDLAND. We stand out for our scientific rigor and validity. Our products are not based on guesswork or theoretical assumptions like many others. Instead, most of our products are validated using experimental or numerical data from valued scientific journals. Even if direct validation isn’t possible, we build our models and assumptions on the latest research, typically using reference articles to approximate reality.
Yes, we’ll be here . If you have trouble loading files, having technical problems, or have any questions about how to use our products, our technical support team is here to help.
You can load geometry and mesh files, as well as case and data files, using any version of ANSYS Fluent.
