Title of Presentation:
3D CST Simulation of the IEC 61000-4-4 Test Setups for Signal Cables using Capacitive Coupling Clamp

Abstract:
The presentation is devoted to the use of the CST simulator (cable studio and Design studio) for the simulation of some test setups in accordance with the IEC 61000-4-4 standard dedicated to EFT transient disturbances. Coaxial and shielded cable structures with two symmetrical and non-symmetrical conductors are considered at Auxiliary Equipment AE and Equipment Under Test EUT side.. In particular, we analyze which decoupling devices are useful to place between the capacitive clamp and the AE. Comparisons of currents on screens and loads are reported between 3D CST simulations, SPICE and measurements.

Title of Presentation: 
3D Fluid-Structure Interaction Simulation with a Novel Reconnection Based Arbitrary-Lagrangian-Eulerian Approach

Abstract:
Fluid-structure interaction (FSI) explores the dynamic interplay between fluids and solid structures, which is crucial in understanding Natural phenomena and engineering applications.
In the literature, an Arbitrary Lagrangian Eulerian (ALE) approach for Navier-Stokes equations is widely adopted to simulate FSI problem with moving boundaries. However, the main disadvantage is to being able to handle mesh distortion when large displacement and deformation occurs.
In this context, we proposed a novel remeshing procedure based on mesh connectivity manipulation and refinement. The new algorithm aims to reduce the remapping of solutions after mesh modification, preserving the solution accuracy.
In the FSI setting, we applied a partitioned scheme to deal with solid and fluid numerical solver separately. The solid subdomain will be investigated using the out-of-the-shelf solver Abaqus/Standard, thanks to its highly efficient and comprehensive library of structural elements, including shells, membranes, and beams, as well as its extensive collection of pre-built constitutive. Finally, to manage the coupling conditions, we exploit the SIMULIA Co-Simulation Services (CSS), a software component for run-time coupling of simulation tools. Moreover, we selected a Gauss-Seidel coupling method consisting of a staggered and sequential scheme, where fluid and solid are solved iteratively until convergence on the interface region is achieved.
Several benchmarks are presented to validate the FSI solver, as well as engineering application in biologic and sailing fields.

Hybrid Anthropomorphic Test Device Model for Efficient Simulation of Crash Scenarios

Abstract:
The work describes a numerical technique to represent aeronautical and pedestrian crash scenarios, aiming at investigating impact conditions that are then used to design efficient energy absorbing structures and devices, thus enhancing the crashworthiness of vehicles. A hybrid approach, i.e. the combination of Finite Element (FE) and Multibody (MB) techniques, has been adopted, and the models have been developed using SIMULIA Abaqus/Explicit. The two Anthropomorphic Test Devices (ATDs) described in the work can be used to efficiently perform parametric studies of crash scenarios, and thus this approach can usefully drive the design process.

Simulation of Free-Surface Fluid-Structure lnteraction Problems Employing Particle Finite Element Method and ABAQUS/Explicit

Abstract:
Fluid-structure interaction (FSI) problems are of great relevance in many engineering fields. This work introduces a partitioned scheme combining an in-house solver Particle Finite Element Method (PFEM) for the fluid and ABAQUS/Explicit for the solid subproblem.
The PFEM is particularly effective for solving problems presenting free-surface, propagating waves and evolving interfaces between fluid and solid. To guarantee an efficient solution scheme, an explicit time integration is performed. Meanwhile, ABAQUS/Explicit enables handling complex structural materials, diverse finite element types and complex inter-body interactions.
The coupling between the structure and fluid is achieved by exploiting the SIMULIA built-in Co-Simulation Service incorporating the Gravouil and Comberscure (G&C) algorithm. The method guarantees a streng and stable coupling between the fluid and solid solvers while maintaining an overall system of fully decoupled explicit equations.

Title of Presentation: 
Vibro-Acoustic Simulation for Truck Tire Tread Noise Prediction

Abstract:
In the last years, the introduction to the market of electric vehicles and a new labeling system introduced by the European Commission raised a strong interest in the noise produced by the tire-road interaction. The reduction of noise emissions became a strong challenge for the tire manufacturers that are constantly in need of developing new simulation tools capable of predicting the noise emitted by a tire.
The application of a simulation methodology capable of predicting the noise performance of a tire is shown and validated by means of experimental data. The experimental activities consisted of the acquisitions of noise produced by three truck tires made up of a particular tread pattern in which a single geometric feature is analyzed in each configuration, in a near field indoor condition.
The simulation process aims to faithfully reproduce the procedure of the experimental test and involves the use of non-linear explicit finite element analysis followed by a vibro-acoustic simulation to account for the radiated noise by structural vibrations and fluid-pumping.
