Finite Element Analysis (FEA)

Finite Element Analysis for robust and predictable system performance

Nobleo designs complex high-tech systems that must perform reliably in challenging environments. Finite Element Analysis (FEA) is an important part of our modelling approach, enabling us to meet demanding system requirements while improving accuracy, repeatability and robustness.

Designing advanced mechatronic modules requires clear insight into system behaviour to predict and ensure performance. By identifying critical design drivers early, FEA supports efficient optimisation and fast-focused redesign throughout the development process.

Effects such as floor- and flow-induced vibrations, structural loads and thermal influences impact system performance and lifetime. Understanding and mitigating these effects is needed to ensure durability and compliance with specifications.

Verification and validation through simulation

Using FEA, we model and analyze system behavior to identify dominant compliances, understand how deformation propagates through the structure, and evaluate how mass distribution affects dynamic behavior.

We apply a wide range of analyses, including structural, modal, harmonic, and random vibration analysis, as well as thermo-mechanical simulations and thermal analysis in both steady-state and transient conditions. These analyses enable us to assess system stiffness, stability (including buckling), thermal performance, and lifetime under realistic operating conditions.

FEA also supports mass optimization, allowing us to redesign mass distribution to improve dynamic performance and reduce sensitivity to vibrations. By identifying performance issues early in the simulation phase, we iterate on the design and implement targeted improvements. This reduces the risk of costly redesigns and project delays.

Integrated system approach

By making dynamic and thermo-mechanical behavior explicit and quantifiable, FEA enables us to close the loop between mechanical design, system dynamics, and control engineering. It acts as a bridge between design and control teams, supporting efficient collaboration and faster convergence towards an optimal design.

Within Nobleo this core structural and Multiphysics tool is embedded in the Nobleo Design Core. It is applied throughout the product development process to ensure robust, predictable, and high-performance systems that meet both functional and lifetime requirements.
