Liam Stephen

Forward thinking Mechanical Engineering graduate with a strong foundation in CAD design and modelling and simulation. Proven ability to translate theoretical concepts into reduced order modelling for simulations but also into physical prototypes, evidenced by improving an adaptive wheel chair during a 6-month project that improved the ergonomics to meet the changing needs of the patients.

Extensive experience with various CAD programs including 3 years in Creo Parametric, 2 years in AutoDesk Inventor, Ansys Parametric, Granta Edupack and Solid Works. seeking to contribute technical precision and problem-solving to for real world problems.

• Honours project created a reduced order model of a full simulation using Proper Orthogonal Decomposition which greatly improved the efficiency of the simulation.

• Energy content of the simulation was divided into 400 “modes” in which the reduced order model correctly identifies the top 10 highest energy content modes which contain 99.8% of the simulation’s energy. The rest of the 390 modes were removed and the simulation retained a 99.8% accuracy.

• Masters project which designed a wheelchair for users with degenerative spinal issues, incorporating a system to allow for an automatically adjusting backrest to provide maximum comfort and safety to the patient as their condition progresses while examining ergonomics, circular economy and safety measures. Designing a magnetic braking system using Eddy currents for soft breaking for the user.

• By using an Electro Magnetic Force reader, various materials and thicknesses with different material combinations were tested to find the most effective way of creating Eddy currents to create the resistance needed as well as testing various magnet types.

• Recreating Retro Computers in Autodesk Inventor and independently designing retro computer cases from media sources then researching materials using Ansys Granta to create a suitable material selection for the case.
• Weekend Sailing Club - Participating the local sailing club for 6 years, achieving RYA level 1
