ENGINEERING PORTFOLIO

Nathanael Smith

Mechanical & Mechatronics Engineer

Mechatronics Engineering Student · Adelaide, Australia

I build multidisciplinary engineering systems across embedded software, control, physics-based modelling, simulation, optimisation, and mechanical design—using models to expose trade-offs before hardware exists.

From physics to implementation. Projects are carried from physical constraints and first-principles models through simulation, optimisation, software, and design.

Coupled-domain modelling. Mechanical, hydraulic, control, and software effects are treated as interacting parts of one system rather than isolated tasks.

Evidence before claims. Results are cross-checked against analytical benchmarks, physical limits, and numerical uncertainty before they are presented.

01 / FLAGSHIP CASE STUDY

Flagship Project — Results at a Glance

Ownership, project scope, and key quantitative results are surfaced here first. The full case study carries the modelling, assumptions, verification, and supporting artefacts.

Hydraulic Radial Piston Motor Design and Optimisation

Physics-informed design and optimisation of a radial piston hydraulic motor for mining-duty conditions, coupling cam geometry, compressible hydraulic dynamics, structural analysis and harmonic torque-ripple behaviour.

Revised after submission — mathematical derivations and optimisation results expanded for portfolio clarity.

02 / DOMAIN DEPTH

Domain Depth Profile

A view of how deeply the flagship project exercises each engineering domain. With one published system, depth is more informative than a cross-project matrix.
