COMPUTER AIDED ENGINEERING (CAE)
Supashock has a proud history of product design and development, from an initial idea through to in-service proven systems. Essential to this is an advanced and highly integrated Computer Aided Engineering (CAE) process.
Using Multi-Body Simulation (MBS) to determine design loads, inform preliminary components sizing, and confirm overall system functionality,
Explore options to reduce component weight using Topology Optimisation,
Verifying component strength meets requirements outlined in industry standards or specified by clients through Finite Element Analysis (FEA),
Assessing fatigue life for a given load spectrum and design life requirements, and
Checking tooling processes and functional design clearances for production.

SUPASHOCK ENGINEERING ANALYSIS EXAMPLES
Multibody Simulation (MBS) is used to simulate the motions and loads within mechanical systems. It can be used to check functionality in a virtual environment before committing to prototype production. Supashock has used MBS in defence projects where our team was able to optimise system kinematics, minimise deployment times and actuator loads of a mechanical device.
MBS can also be used to analyse more complex systems, such as an entire car. Here, Supashock simulated a car racing around a track, calculating suspension forces based on tyre grip, inertial and aerodynamic loads.
Using Topology Optimisation, Supashock can save weight and maximise structural performance. In this example, Supashock used Topology Optimisation to “eat away” weight out of a payload support, while maintaining load carrying capacity. Supashock then took the resulting shape, and developed it into a production ready component.
The image (left) shows the Topology Optimisation process, from the Original Design, to the Optimised Design, and finally the Production Ready Design.
Supashock makes extensive use of FEA throughout the design process. Here, structural stresses in Supashock’s Automatic Load Handling System (ALHS) are assessed throughout a lifting cycle. This sort of whole-of-system model is used to confirm component loads, identify highly stressed areas for further analysis or, conversely, identify low stress regions to target for weight saving.
Using Explicit Dynamics and the LS-DYNA software, Supashock can also solve highly non-linear problems that are normally impossible using conventional FEA. These include situations such as crash loads, ballistic impact, or situations where material damage or failure is encountered. In this example, Supashock simulated a rigid impactor striking a 60-millimetre diameter carbon composite tube at 8.8 meters per second. With Explicit Dynamics, the progressive failure of the carbon tube is captured, providing a measure of the true strength and impact resistance of the tube.
Our team of experienced analysis engineers can offer any or all these services to clients. Supashock can also work directly with clients to optimise designs, whether it be to achieve weight savings, improve performance, or simplify fabrication processes.
