Reality-inspired simulations

EikoTwin Digital Twin

EikoTwin Digital Twin allows the engineer to improve their simulation calibration process by making the most of their test data.

It implements "augmented simulations", which use the measured data as boundary conditions, but also allows the simulation calibration of material parameters to bring the simulation closer to the expected result.

Principle

  • Integration of test results for the validation of simulations.
  • Import of sensor measurements and direct comparison with the simulation result.

Features

  • Use of measurements to enrich the simulation model.
  • Creation of measured boundary conditions to release idealized conditions.
  • Export of a simulation model enhanced with measurement information.

Results

  • Quantification of errors due to boundary conditions.
  • Automatic identification of the simulation parameters required (materials, etc.).
  • Determination of the residual model error.

Testimonials

IRT Saint Exupery

Using EikoTwin allowed us, through augmented simulation, to correct overly idealized boundary conditions, or to isolate regions of interest. The inverse identification proposed by Digital Twin also gave very promising results for reviewing the calibration and validation processes of the models by reducing the number of tests.

Integrating multi-camera DIC at MBDA

Image

As part of its increasing competence in cutting-edge measurement techniques, MBDA has launched a process of testing and internal auditing of measurement resources by multi-camera DIC (Digital Image Correlation). After testing these measurement tools on coupon-type test campaigns, a new stage has been launched with the testing of this technology on more complex structures using multi-camera systems.  Compressive…

Crash-test and image correlation: how to measure seat deformations and follow the dummy’s movements

Senza Titolo

Crash-tests are a crucial step in the development and certification of products, especially for the automotive, aeronautical and railway industries. These tests simulate collision or impact scenarios in order to evaluate the resistance and safety of products. Among the equipment used to perform these tests is the reverse catapult, which is a device that projects…

Digital Image Correlation (DIC) for vibration analysis

Image6

Digital Image Correlation (or DIC) is well-known for its static applications, but under the right circumstances, it is equally applicable to vibration testing. Here is as industrial example at Safran. As part of the development of increasingly high-performance aircraft actuators, Safran Landing Systems (SLS) must ensure the integrity of its systems during commissioning. With this…

How ArianeGroup improves simulation credibility with EikoTwin and DIC

&

Simulation credibility is a key aspect of the Virtual Testing concept. As the European leader in space launchers, Ariane Group participates with EikoSim in multiple Research and Development projects, including a RAPID R&D project (“MUTATION”) funded by the Direction Générale de l’Armement. This project aims at developing an industrial platform for test-simulation dialogue to meet…
