ANSYS Simulations

Nonlinear Contact Analysis of Rubber O-Ring

The O-Ring assembly was created in Design Modeler and an analysis was run to determine the deformation and stresses of the ring when being compressed by the other components in the assembly. A maximum stress of around 3000 kPa was observed and the deformation of the O-Ring pushed the object into the corners of the assembly components.

Torsional Rigidity of Formula Frame

The analysis was run for the 3D formula frame shown above. The frame was created with Design Modeler and uploaded to ANSYS Workbench. The loading condition and constraints were to have the frame fixed at the rear nodes of the engine frame. Also two forces, measuring 170 N are applied in opposite direction to simulate a moment at the front of bulkhead supports. The member is circular tube made of structural steel.

Thermal Analysis of Pump Housing

To conduct the analysis for the pump housing the file needs to be downloaded and converted in STEP format. Once uploaded to Workbench a thermal stress analysis system can be selected where the geometry can then be imported. The pump housing has two temperature boundary conditions, one at the mating surface of the housing at 60 °C and another throughout the interior of the housing at 90 °C. A convection will also be applied on the outside of the surface. A temperature and heat flux contour plot can then be generated where it is clear that the fluid is drastically heating the interior geometry of the part. Stress plots are also generated which slow relatively low values and a total deformation of less than a millimeter. However, the factor of safety is less than 1 which shows that the part fails testing. The safety factor map shows high regions all throughout the model, especially towards where the part is bolted down

Conjugate Heat Transfer Analysis of Cross Flow Heat Exchanger

This assignment used the fluid-soild heat transfer add-in of ANSYS AIM where a heat exchanger was analyzed. A streamline plot of the pressure can be seen along with temperature plots throughout several cross-sections and a temperature plot. The heat exchanger assembly was downloaded and uploaded to analyze.

The solid model was downloaded and uploaded to ANSYS AIM for analysis. The results showed a temperature of 321.15 K at the outlet and a velocity of 4.9379 m/s. This simulation featured a fluid flow analysis with various boundary conditions to simulate a flow in a mixer. Results were run to show the temperature distribution as well as the velocity distribution as the fluid moves around the mixer.

Flow in a Ball Valve Assembly with Y Connector

The valve was downloaded and uploaded for analysis. For this simulation we were able to use ANSYS AIM to run a fluid flow analysis on a ball valve with a split outlet. The mass flow is able to stay consistent as shown in the results and the velocity, pressure and several stream line plots showed how the fluid moved throughout the geometry. The pressures and mass flow rates of the outlets do not match due to the varying geometry of the actual valve.
