Material Selection and Computational Analysis on DOHC V16 Engine’s Mounting Bracket Using COMSOL Multiphysics

M. V. A. Nag[1]
[1]G.R.I.E.T., Hyderabad, AP, India

Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. The usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. This ...

CNRS, LAAS, Toulouse, France

3D electro-thermo-mechanical finite element model of power vertical MOSFET used in the automotive industry is presented in this paper. The presented paper is a qualitative study of power device results from electro-thermo-mechanical simulation. This study particularly interested in the stress generated at the interface between the bonding wires and the source metallization to evaluate the ...

A Multiphysics Approach to the Modeling of Biological Prosthetic Heart Valves

A. Avanzini[1], D. Battini[1], M. Berardi[1]
[1]Università degli Studi di Brescia, Brescia, Italy

The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set loads, boundary conditions and implement anisotropic hyper-elastic constitutive laws for leaflet tissue, PDE to ...

A Computational Approach for Optimizing the First Flyer Using COMSOL Multiphysics

A.H. Aziz[1], H. Pourzand[1], A.K. Singh[1]
[1]Pennsylvania State University, University Park, PA, USA

COMSOL Multiphysics software was used to structurally optimize the Wright brothers’ flyer. The flyer was drawn in SolidWorks, imported and meshed in COMSOL. COMSOL Solid Mechanics module was used to analyze the flyer. Four of the sixteen struts were removed yet the structural integrity of the flyer was maintained. COMSOL Laminar Flow module was used to compute the aerodynamic forces and ...

[2]Heerema Marine Contractors, Leiden, The Netherlands

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...

Simulation of Microstructured Rolling-Sliding Contacts - new

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...

Structural and Environmental Design of a Rainscreen System Using COMSOL Multiphysics

C. Guido Galante [1], M. Donà [2],
[1] Newtecnic Ltd, London, England, UK
[2] University of Cambridge, UK

The subject of the study is a bespoke rainscreen system designed for the Grand Theatre of Rabat, Morocco (Figure 1). The project presents a complex façade geometry and consists of a 1800-seat theater, an open-air amphitheater with a capacity of 7000 people, a rehearsal space and a restaurant. The rainscreen system consists of fiberglass individually cast reinforced concrete (GRC) panels ...

Simulation of the Thermal Expansion of an Inductively Heated Gear Wheel for Shrink Fitting Purposes

C. Hollenbeck [1], Z. Jildeh [1], T. Rydlewski [1], P. Kirchner [1],
[1] Imagine Engineering GmbH, Bergheim, Germany

Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal expansion as well as the shrink fitting process. It was possible to find an appropriate geometry for the induction ...

Design and Simulation of MEMS Based Gyroscope for Vestibular Prosthesis

[1]Department of Biomedical Engineering, PSG College of Technology, Coimbatore, Tamilnadu, India

The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often characterize dysfunction of the vestibular system. Our aim is to design vestibular prosthesis using COMSOL ...

Simulation of Wear using LiveLink™ for MATLAB®

D. Sutton[1]
[1]National Centre for Advanced Tribology at Southampton, University of Southampton, Southampton, United Kingdom

An incremental wear model has been developed using COMSOL Multiphysics® with MATLAB® to predict the evolution of component geometry as a result of wear. Whilst Archard’s wear law is a well-known empirical model for the prediction of wear volume, the design engineer is interested in changes in tolerance as a result of component geometry. At each time step, the simulation extracts the pressure ...
