Hyper-reduced models of hyperelastic dissipative elastomer bushings

2020-09Abstract
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.
