FE SIMULATIONS AND ANALYSIS

Pillar of industry 4.0

FEM SIMULATION

FEM (finite element method) simulations and discretization of continuum provide us with very satisfactory results in technical practice. These mathematical virtual models for verification of product behaviour and functionality can be simulated without the need to test physical samples. However, in some cases, simulation results are insufficient, and the generation of complex virtual models must be validated through physical test results.

BENEFITS OF VIRTUAL SIMULATIONS

Significant reduction of time in development
Reduction of costs of development
Prediction of mechanical behaviour without physical testing
Detection of structural bottlene points
Possibility of optimizing the design for selected test scenarios

OFFER OF SERVICES IN ANALYSES AND SIMULATIONS

In the field of virtual testing CAE (Computer Aided Engineering), we focus on structural static and dynamic stiffness analysis. We use both common mathematical procedures, as well as generated FE-models. Thanks to these simulations, we can detect structural weaknesses prior to the start of manufacturing. We carry out optimization of the structural parameters and/or shape and propose DoE virtual experiments. We often use laboratory testing of materials or physical samples to validate complex virtual FE-models. We focus mainly on work machines, automotive industry and mechanical engineering; however, our methods and procedures can be applied to other industries such as the army and railways. Numerical modelling can be used either on its own to validate customer’s design and/or as a support activity in development and design works.
