Numerical simulation

 

V2i takes in charge the whole project: from the definition of the objectives and model hypotheses up to results interpretation and correlation with experimental data.

Hypotheses - Objectives definition

V2i relies on the expertise and experience of its engineers to define the hypotheses of the study in accordance with the objectives to fulfil.

This expertise and know-how in modelling lies in the partnership between the Aerospace and Mechanics Department of Liege University, a pioneer team in the development of Finite Elements Method, and V2i.

V2i has the required tools to import your CAD design and to apply the required modifications for the meshing step.

Modelling

Regarding objectives to fulfil, V2i can perform the meshing of your structure using any kind of element:

  • 1D elements: bars or beams
  • 2D elements: membranes or shells
  • 3D elements: volumes and axisymetrical, multi-harmonical, ...

It is also possible modelling a wide range of materials, linear or non-linear, isotropic or anisotropic like composites.

Studies

V2i can offer a wide variety of studies, for example:

  • Static: displacement and stress computation
  • Lifetime prediction of structures through cumulative damage computation
  • Dynamic: mode shape computation and related resonant frequencies
  • Rotor dynamic: critical speed and Campbell diagram
  • Response computation under random or harmonic excitations
  • Non linear time response computation

Results analysis and correlation

Regarding tis complentary expertise into experimentation and measure, V2i enables you a full exploitation of the results provided by the numerical simulations:

  • Results comparison with a modal analysis and model updating
  • Simulation of a vibration test and check of the structural integrity during the test
  • Correlation of stress gauges measures with model predictions

V2i assets

  • Flexibility and responsiveness
  • An integrated service combining its expertise into structure modelling and experimentation
  • Lifetime prediction of your structure or component
  • Vibration tests simulation
  • In-depth and clear analysis of the results

Some examples of performed studies

  • Verification of the structural integrity of composite mechanical parts and computation of their resonant frequencies
  • Wind resistance modelling of street lights, pole and fixture design
  • Computation of stress, eigenfrequencies and eigenmodes before test and study of the coupling between the equipement to be tested
  • Campbell diagram computation of a shaft and comparison of critical speeds with nominal running range.
