"A review of bushing modelling approaches for MultiBody simulations" "Rocco Adduci, Martijn Vermaut, Simon Vanpaemel, Frank Naets" "Rubber bushing elements are largely used in different industrial sectors thanks to their ability to withstand large reversible deformations and attenuate vibrations. Nonetheless, they are complex mechanical components that present several nonlinearities with respect to the excitation amplitude, frequency and operational temperature. These characteristics are the result of phenomenological features, such as nonlinear elasticity, viscoelasticity and Mullin’s effects, that are challenging to be accurately represented in simulation environments. An additional level of complexity is then encountered when such components are included in system-level models. This work provides a general overview of rubber bushing properties and analyses different strategies to formulate bushing elements in Multibody frameworks that can be used as Virtual Sensors to predict physical quantities difficult or impossible to directly measure in the real systems. Constitutive lumped parameters models are reviewed and discussed with particular focus on the overlay approach."

"Modeling of complex moving sound sources using a cut finite element method approach" "Sjoerd van Ophem, Wim Desmet, Elke Deckers" "While acoustic analysis with the finite element method is commonly done under the assumption that the source location is stationary, this is not always a valid assumption. This article derives a method to simulate moving sound sources using an unfitted mesh approach, where the source boundary is described by cutting through elements, known as the cut finite element method (cutFEM). By using such an approach the mesh stays static during simulation, even for large source movements, thus avoiding expensive re-meshing or mesh morphing steps. To be able to describe a wide variety of acoustic sources, both sources with a large and thin thickness are considered. Several time integration schemes are assessed and a method to determine the stability of the resulting time-varying system of equations is derived. The article concludes by demonstrating the derived methods with two examples, where it is shown that the unfitted mesh approach is a viable way to simulate moving sources."
