Modelling & Simulation of the Rear Suspension of a Fly Car (Aug 2017 – May 2018)

The aim of this project was to design, simulate, conduct Finite Element & Fatigue Analysis of the rear suspension of a vehicle that can be used for dual purposes – a car & a flying vehicle – that can withstand with rapid changes in forces.

Responsibilities

• Investigating & evaluating different types of suspension systems before selecting optimum suspension for project.
• Conducting an in-depth study of Finite Element & Fatigue Analysis of rear suspension system, i.e. assessing the durability and life cycles.
• Conducting an in-depth study understanding the effects of aircraft weight & altitude on basic Height Velocity (H-V) diagram.
• Calculating vertical, radial & longitudinal forces during different manoeuvres, particularly during crash landing.
• Studying properties such as crack propagation of different types of materials & using CES Edupack for comparing material properties.
• Working in collaboration with other teams on the project e.g. the chassis team.
• Weekly consultation with my unit’s supervisor, client; writing & maintaining a weekly progress report.
• Compiling a final report on the project that includes literature review & results.

Achievements

• Selected MacPherson Suspension System.
• Used Variable amplitude (VA) load curve instead of Amplitude Curve (AC) in order to achieve optimal results for stress concentration on suspension structure.
• Identified through VA load study curve that lug had highest concentration area with a displacement of 0.21mm. Therefore, Fatigue study to be conducted on lug.
• In order to reduce displacement of lug further investigation was conducted on design & material properties. As a result, high tensile chromium A519 steel was replaced by A1011 A36 grade steel to decrease displacement.
• Following adjustments above the Palmgren-Miner rule was applied, revealing total life cycle of suspension system was calculated as 9.9 × 107 cycles. Each cycle was 2700s based on the S-N curve modelled initially. Suspension life was predicted to be 300,000 kms for entire life cycle.
• Completed a report that summarises literature review findings and justifing design choices.

Formula – SAE (Society of Automotive Engineers)

Dynamics Design Engineer (Feb 2017 – May 2018)

Formula SAE is an international competition among students to conceive, design, fabricate and compete with formula-style racing cars in Australia and around the world.

The aim of the project was to understand, optimise, design, conduct Finite Element Analysis (FEA) and produce engineering drawings of front and rear Uprights for the team Swinburne 2017 (ts-17).

The function of the upright is the following: To provide a physical connection from the wheel to the suspension links(wishbones); connection of steering rod; provide mounting and installation for brake caliper and adjustment of camber and caster angle.

Responsibilities

• An in-depth study re. significance of uprights in racing cars & connected components.
• Conducting force analysis, i.e. calculating the dynamic forces to determine load transfer in each wheel during different maneuverers such as cornering & braking.
• Selecting bearings for wheel hubs.
• Investigating different materials, comparing their properties such as tensile strength, density, stiffness & easiness to manufacture.
• Conducting Finite Element Analysis for factor of safety (FOS) & design optimisation.
• Establishing good rapport & clear communication with team members to facilitate effective team work & sharing of information.
• Attending weekly team meetings for progress checks and discussion re. sponsorships.

Achievements

• Successfully managed a team of 8 members teaching them how to budget, design and produce an entire vehicle, manage sponsors and suppliers, and develop a long-term plan.
• Successful met project deadlines including week 7, 80% design review and week 12 project completion.
• Developed an Excel file for future team members re. force analysis.
• Designed & optimised uprights on Solidworks (CAD software) by conducting FEA on ANSYS & reduced 10% weight compared to ts-16.
• Selected Deep Groove Ball Bearing NTN 6908VV instead of Angular Contact Ball Bearing NSK 7908C after in-depth research & contacting suppliers. As they were 5 times less expensive, freely available & offer less rolling resistance.
• Calculated Bearings life span & learned that the minimum time before a bearing fail is 2,500 km.
• Selected Aluminium T6-7075 was the optimum material due to its weight and ease to CNC.
• Used ANSYS 17.2 to conduct FAE; forces were applied remotely on the upright at contact patch & achieved a FOS of 2.2.
• Prepared 2D Engineering drawings of front & rear upright with all specifications such as tolerances for manufacturing.
• Applied feedback from alumni & senior team members re. the design of uprights & made relevant changes.
• Successfully recruited 5 sponsors such as Accurate CNC & Tyre Power worth $8,000.
• Highly appreciated the ‘esprit de corps’ in my project team and opportunity for personal development through the application of our theoretical knowledge to practical problem and their solution.

Extra-curricular Activities

Social Issues

Having a great passion for understanding social issues that exist within a society, world affairs and the role of mass media plays to highlight these problems, I enrolled in a Journalism unit called News Writing. I particularly enjoyed this unit because there was high level of engagement within the class and with the tutor. Discussions were lively and I was commended for my active participation & contribution.

Following are my achievements in the unit:

• Conducted & wrote an interview with Behran Ahmed – chief executive of African Think Tank and scientist at Melbourne University – to find out the particular challenges faced by the African community in Australia.
• In another article, I highlighted the problems faced by families involved with Very Special Children – an organisation for terminally ill children.
• New insight into Australian culture and society.
• Training in meeting strict requirements of News Writing, e.g. presenting news very succinctly and in a manner that engages readers from the first paragraph; accuracy & fact checking; interview techniques and using quotes effectively.

Lego

Having always found Lego projects very useful tools through which I could exercise understanding of design.

• I have assembled Lego sets such as Mercedes truck and GTRS.
• Currently I am constructing a Lego project (EV3) that involves computer program in order to learn more about programming and robotics.
• In addition, this will help me provide with the practical knowledge to develop my own Lego design.
