Résumé

Rubber mount modeling in multibody simulation is crucial for accuracy in this type of calculation, and despite its importance, they are often underestimated in terms of modeling. The present work aims to develop and implement a finite element model suited for rubber behavior in large deformations, and apply hyperreduction techniques to evaluate the possibility of a direct implementation into a multibody simulation, or to generate a novel family of joint models. The article begins with the development and implementation of the material behavior, then a brief explanation on the implemented finite elements routine along with the hyper-reduction method used. An analysis of the results and an insight of future developments closes the article.

  • Dissipation in hysteretic rubber mount models 
    Communication avec acte
    PENAS, Rafael; GAUDIN, Arnaud; KREIS, Adrien; BALMES, Etienne (2019)
    Rubber mounts are elements of extreme importance in automotive suspension, and accurate modeling is crucial for comfort design. While mount characterization is typically done using cycles, actual performance is often ...
  • A unified non-linear system model view of hyperelasticity, viscoelasticity and hysteresis exhibited by rubber 
    Article dans une revue avec comité de lecture
    PENAS, Rafael; BALMES, Etienne; GAUDIN, Arnaud (Elsevier BV, 2022-05)
    Rubber modeling is an old subject and so many models exist that it is difficult to have a clear vision of what exists and is more appropriate. Rather than attempting a standard review, this paper proposes classification ...
  • Sensitivity analysis of catenary geometry on current collection quality 
    Communication avec acte
    VO VAN, Olivier; BALMES, Etienne; CAPITAINE, Arnaud; LORANG, Xavier (Civil-Comp Press, 2016)
    A global sensitivity analysis is led on catenary parameters such as dropper lengths, height of the messenger wire at masts and mechanical tensions in the wires thanks to the Sobol indices. All parameters are defined using ...

    Communication avec acte
    ARLAUD, Elodie; COSTA D'AGUIAR, Sofia; BALMES, Etienne (2014)
    In order to face challenges of increased traffic and speed on their infrastructures, railway companies need to develop numerical tools able to predict the dynamic behaviour of the track. Currently, two approaches are widely ...
  • Damping characterization of a high speed train catenary 
    Communication avec acte
    VO VAN, Olivier; BALMES, Etienne; LORANG, Xavier (2015)
    Catenary damping has long been a tuning parameter in pantograph-catenary dynamic interaction models. As the computed contact force is highly sensitive to the choice of damping model or coefficients, it became critical to ...
