Support Structure Design

Support Structure Simulation

Description:

The Capstone Project is the final project assigned to engineering students. The project my team was assigned was to develop and build a sustainable, scalable, and “net positive energy” gravity battery system. This project went through several stages where key subsystem designs were conceptualized, developed, tested, iterated, and improved upon. I played a key role in the development of the support structure subsystem. I also acted as team lead and managed the project following the Waterfall methodology. I was involved in all areas of the project and also played a supporting role in the development, construction, and assembly of the gearbox subsystem. I also machined some of the components using a lathe, such as the shafts used in the gearbox.

Fusion360 Generative Design Aluminum Output

Description:

This project involved using AI to help reduce the time it would take to go from the conceptual phase to the design phase. The project involved programming AI agents in Python using an LLM, which acted as stakeholders. The AI agents were then asked questions to extrapolate key information. Next, a stable diffusion model was used in Python to generate several different possible skateboard designs from the information that was extrapolated. Then, two designs were chosen and modelled in Fusion360. Lastly, the truck and axle assembly for the two designs were put through the Generative Design AI in Fusion360 to produce more optimized or visually appealing variations.

3. Floating IoT Charging Solar Panel

Description:

This project involved creating a floating solar panel that could tilt towards the sun, charge a battery, and connect to your phone (IoT). This project went through three different phases: the conceptual design phase, the embodiment design phase, and the final design phase. The design my team went with utilizes two axes of rotation, where there is a rotating mechanism and a tilting mechanism. The rotating mechanism uses a stepper motor and a planetary gearbox, where the tilting mechanism utilizes a servo motor and a simple pin. The idea behind the final design was to be an emergency beacon that could be deployed on water in times of distress.

Aluminum Output Stress Concentrations

Description:

This case study involved designing a basic hinge and using the Generative Design AI in Fusion360 to optimize, enhance, and alter the design. This was done by first making the model of the hinge in Fusion360 and then adding geometry that would act as obstacle geometry (where the AI cannot add material). A load was placed on the top of the hinge, and the back of the hinge was pinned. Then, the Generative Design AI was utilized to produce variations of the basic hinge design.

Description:

This was the final project for a simulations course and involved combining computational fluid dynamics (CFD) simulations and finite element analysis (FEA) simulations. The main purpose of the project is to design a support structure for a sign that can withstand a hurricane (high speed wind loads). This project involved modelling the sign and the domain used for the simulations. A mesh study was performed on the mesh used in the CFD simulations to find the optimal mesh density to time spent per iteration ratio. Then, CFD simulations were performed on a sign to simulate low and high speed winds. This was to find relevant information that could be used for the loading conditions for the FEA portion of the project. In the FEA portion of the project, a support structure was designed and tested to ensure that the support structure will not break under high speed wind loads.

Density Parameters for Mesh of Tall Building & Domain

Description:

The purpose of this project was to see how placing a structure next to an existing one would affect the wind speed. This project involved modelling the buildings and their domains as well as carefully setting the mesh to ensure that the simulation ran correctly. The results showcased that placing a building next to another results in an increase in wind velocity.

7. Life Cycle Analysis & Impact Assessment of a Metro Train

Description:

This project involved finding an existing life cycle analysis (LCA) for a product and altering it to be more environmentally friendly. My team chose a metro train as the product, and we decided to change two subsystems rather than one, which were the braking system and the HVAC system. This presented a great challenge as the workload for most tasks doubled. The braking subsystem was altered from a traditional braking system to a regenerative braking system, and the HVAC subsystem was altered to include an air curtain. I completed the impact assessment portion of the project and completed all the research for the life cycle inventory analysis.

8. Gear Calculations for Upper Body Ergometer Gearbox

Description:

This project involved conceptualizing, designing, and iterating on an upper body ergometer. This project focused on inclusive design elements, where very low loading values were targeted with high reliability. I performed the gear calculations for the gearbox. This involved taking information found from the cyclical analysis and calculating or analyzing each gear parameter in order to find the safety factor. The minimum target for the safety factor was to be above 1 to ensure that the gearbox does not fail. The calculations for the gears followed the AGMA standards.
