Australia’s Federal Government has announced an A$1.2 billion Critical Minerals Strategic Reserve, backed by a $1 billion top-up to its existing Critical Minerals Facility. With implementation set for the second half of 2026, the Reserve aims to secure critical minerals—lithium, cobalt, nickel, rare earths—through government offtake agreements and strategic stockpiling miningmonthly.com+15anthonyalbanese.com.au+15discoveryalert.com.au+15.
Why It Matters for Mechanical Engineers
This isn’t just political positioning—it’s a major call to action for mechanical engineering consultancies:
Scale and diversification of processing sites – More projects will need robust mechanical systems from crushing and conveying to structural and structural integrity assessments, especially for rare earths and heavy metals.
Advanced processing technologies – Selective stockpiling and refining of critical minerals will require high-precision mechanical design, wear management, and optimization of machinery performance.
Infrastructure and retrofit demand – The Reserve extends the Critical Minerals Facility’s reach to A$5 billion, catalysing greenfield builds and upgrades—areas where Hamilton By Design excels.

Why Both Matter in Mechanical and Structural Engineering
In the fast-paced and high-stakes environment of the Australian mining industry, reliable engineering design isn’t just a competitive advantage — it’s a necessity. Across regions like the Pilbara, Kalgoorlie, the Hunter Valley, Bowen Basin, and Mount Isa, mining operations depend on complex mechanical systems that must perform under extreme loads, harsh conditions, and round-the-clock operation.
To ensure safety, reliability, and performance, mining engineers increasingly rely on advanced simulation tools like Rigid Body Dynamics (RBD) and Transient Structural Analysis (TSA). While these tools might appear similar, they serve fundamentally different purposes in mechanical and structural engineering. Using the right tool at the right time can dramatically reduce downtime, improve equipment longevity, and lower operating costs.
At Hamilton By Design, we bring the latest in engineering simulation and scanning technology directly to your mining operation — wherever you are in Australia. Whether you’re operating in the iron-rich Pilbara, the gold-rich Kalgoorlie, or deep in Mount Isa’s underground hard rock mines, we deliver world-class engineering solutions on-site or remotely.
What is Transient Structural Analysis?
Transient Structural Analysis (TSA) is a Finite Element Analysis (FEA) technique that models how structures respond to time-varying loads. It provides insights into:
Displacement and deformation under dynamic loads
Stress and strain distribution over time
Vibrations and impact response
Fatigue life prediction
This type of simulation is essential when you’re dealing with high-frequency loading, shock events, or long-term structural wear and fatigue. TSA is invaluable for assessing risk in static and semi-dynamic systems across mining sites.
Typical TSA applications in mining include:
Vibrating screens and feeder structures
Crusher housings and foundations
Chutes and hoppers exposed to high-velocity ore impact
Structural skids for processing equipment
Equipment subject to cyclic fatigue (e.g., slurry pumps, reclaimer arms)
What is Rigid Body Dynamics?
Rigid Body Dynamics (RBD) focuses on the motion of bodies under the assumption they do not deform. This tool models:
Position, velocity, and acceleration
Reaction forces at joints and actuators
Dynamic behaviour of moving parts and linkages
Contact, impact, and frictional interaction
Unlike TSA, RBD doesn’t solve for stress or strain. Instead, it calculates the kinematics and kinetics of motion systems — making it ideal for analysing mechanical assemblies where movement, timing, and loads are key.
Common RBD applications in mining include:
Stacker-reclaimer arms and boom articulation
Mobile equipment with hydraulic or mechanical actuators
Diverter chutes and gating systems
Rockbreaker arm kinematics
Conveyor take-up and tensioning systems
RBD also plays a pivotal role in process optimisation and troubleshooting — helping engineers simulate how mechanisms will respond under load, ensuring operational efficiency before physical prototypes are built.
Why TSA Can’t Replace RBD (and Vice Versa)
While TSA includes rigid body motion as part of the total displacement field, it is not designed for efficient or accurate motion simulation. Trying to model the dynamics of a moving mechanism in TSA can:
Lead to slow solve times and high computational cost
Produce unstable results due to unconstrained motion
Provide limited insight into timing, velocity, or actuation behaviour
Conversely, using RBD for structures that flex, vibrate, or wear over time won’t give you the data needed to assess material failure or fatigue.
The takeaway? Use TSA when deformation matters. Use RBD when motion matters. Use both when you need the complete picture.

When to Use Both Tools Together
A real advantage emerges when RBD and TSA are used in combination:
RBD identifies dynamic forces and timing on moving parts
TSA then evaluates the structural response to those forces
For example, in a diverter chute:
RBD determines the acceleration profile, impact forces, and system timing.
TSA uses that input to analyse whether the chute will survive years of repeated service.
This integrated approach results in more accurate models, fewer design revisions, and significantly lower project risk.
