Crash-test and image correlation: how to measure seat deformations and follow the dummy’s movements
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
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…
Digital image correlation for automotive structures
By Floriane Soulas, R&D Engineer at EikoSim Context In the context of monitoring large-scale production automotive parts, many parts are subjected to repeated tests to ensure their integrity once they are put into service. Thus, the test that we address in this paper is dedicated to the “gust of wind” tests of an opening structure (see…
EikoTwin DIC and the measurement of small strains
By Lucas Angénieux, Research engineer at EikoSim Innovation in the automotive industry Innovation is at the heart of the automotive industry: autonomous vehicles, shared mobility, advanced equipment, etc. In order to reinvent themselves and remain competitive, it is necessary for automotive industries to innovate and develop new technologies. It is therefore essential for these companies…
Design and validation of laser impact tests
By Clara Minguet, Research engineer at EikoSim ALPhANOV, optics and lasers technology centre based in Talence since 2007, and MBDA, European leader in the Defence sector, have had a joint laboratory since 2019 for laser-matter interaction comprised of a cabin equipped with a high-power infra-red source. Thanks to a flexible and durable architecture, complex experiments,…
Detection monitoring of cracks with Digital Image Correlation: a choice tool
By Floriane Soulas, R&D engineer at EikoSim Context Some structures have a long service life from commissioning to replacement. These structures, when they have a fundamental role, must be able to maintain their physical integrity throughout their service life. To do this, it is essential to ensure their reliability over time. In the case of such…
Digital Image Correlation for lattice structures
By Florent Mathieu, Ceo of EikoSim Philippe Brammer R&D engineer at EikoSim Ludovic Barrière, Project Leader: LASER – IRT Saint-Exupéry Why use Digital Image Correlation when testing lattice structures ? This is what this article is about. Interest in lattice structures is growing rapidly for the development of aeronautical and space components in particular. In…
Digital Image Correlation for production monitoring – a collaboration with Renault and CETIM
By Pierre Baudoin, R&D engineer ata EikoSim Context As part of the large-scale production monitoring of automotive parts, it is essential to ensure that the reliability of the manufactured parts remains constant throughout the part’s production cycle. In order to make sure of this, parts are regularly sampled from production lines and tested to ensure…
Validation of a mechanical test – a collaboration with MCE-5 DEVELOPMENT and MECATEST
By Philippe Brammer, R&D engineer at EikoSim EikoTwin DIC to validate your test kinematics, with MCE-5 DEVELOPMENT and MECATEST The purpose of a mechanical test is to submit a part or an assembly of parts to a specific stress in order to evaluate its elementary or in-service performances. The strong hypothesis, strengthened by theory or…
Toward quantitative image analysis of Bird strike tests
By Florent Mathieu, Ceo of EikoSim Redactors : N. Cordero, F. Fremy, M.Beneck for Saint-Gobain, F. Mathieu for EikoSim Aircraft radomes produced by Saint-Gobain are made of composite materials. In addition to the usual design requirements that these structures must comply with (lightness, aerodynamic shape, impact resistance), they need to be RF transparent so that the systems…
