Simulation tools are an important part of a product designer's toolkit. Simulation allows you to test your designs virtually long before physical parts are available. Use FEA and other simulation tools to shorten product development leadtimes and reduce development costs.
FEA Simulation - virtual prototyping
Bayly’s team uses a variety of different design, engineering and analysis simulation tools as part of our design process to deliver high quality product design outcomes to our customers.
3D CAD Model – the core of virtual prototyping
The FEA model is created from the same 3D CAD model that is produced during the detail design activities of the development process.
What do we use FEA to do?
We use FEA to simulate the structural mechanics of a component or assembly of components under the physical loads (forces, gravity, accelerations, vibrations, heat sources etc.) that we assume will be applied to the product in the environment.
An FEA analysis will provide a visual representation of the stress level distribution induced in a component under the assumed loading conditions of the simulation. These stress levels can be compared against the stress limits of materials such as the material yield stress, ultimate stress or at fatigue stress limits.
Rubbish In = Rubbish Out
As in all analysis, simulation and modelling, assumptions need to be made. The results of the analysis are influenced by the assumptions we use and the way the model is setup and this is where experience and knowledge is vitally applied to get useful results that can be used in the development process.
The ANSYS simulation software that we use at Bayly provides us with Finite Element based analysis (FEA) capabilities to simulate the behaviour of systems and components in linear structural and dynamic mechanics and non-linear thermal dynamics.

Simulation and National Standards
Commonly, FEA simulations are not used when analysing compliance to Australian Standards and international standards. In these cases, standards refer to traditional computational techniques and safety factors derived from empirical data and theory that are usually defined in referenced standards and include reference stress limits, deflection limits, buckling limits and more. Scope can exist in standards for compliance through testing and other methods, but these are generally not practical for an application other than in an experimental sense.
