Challenges in the Finite Element Analysis of Tire Design using ABAQUS

Finite Element Analysis of Vehicle and Tire has become a very important aspect of a tire design and failure analysis to most Tire companies. Tire modeling with ABAQUS is a very complicated process involving complex materials like hyperelastic rubber and textile reinforcements, large model size, prolonged simulation time and various convergence issues. This white paper intends to help in understanding the challenges in tire analysis and several tips and tricks that makes a difference in the quality of the results and processing time. AEG hopes that this article will be useful to ABAQUS users working in the field of tire design and analysis. A general tire has the following major tire components Tread Belt Region Inner LinerSidewall Region Inner Carcass RegionBead Filler Region Apex/Chafer Region Beads Reinforcements Nylon Cap Ply Steel BeltsCarcass Ply Constructing the structure of the tire and modeling of each component is the first step into the analysis.

AEG Carbon Fiber-Elastomer Composite Bipolar Plate for PEM Fuel Cells

AEG Carbon Fiber-Elastomer Composite Bipolar Plate for PEM Fuel Cells
Fuel cells constitute one of the most promising sources of environmental friendly energy for the future. These systems produce electrical energy by converting the chemical energy stored in a fuel, such as hydrogen or methanol, through oxidation-reduction reactions. A proton exchange membrane (PEM) fuel cell is a stack of electrochemical cell systems (Figure) placed in series. Since the electrons must transit from the anode of one cell to the cathode of the next cell, electrical conductivity through the plate is a main requirement. Another important requirement is the low permeability to the reacting gases or to ions. The bipolar plates should remain chemically inert for an extended period of time. The bipolar plates also should be lightweight and easily manufactured using mass-production technologies. Cost reduction is the most critical issue for automotive industry to achieve the practical use of proton exchange mem…

Noise, Vibration and Harshness (NVH) Analysis by American Engineering Group (AEG)

Noise, Vibration and Harshness (NVH) Analysis by American Engineering Group (AEG)NVH analysis provides essential benefits towards designing vehicles for ride comfort and quietness, an increasingly competitive advantage in today's global automotive market. The design of a car body structure is decisive in order to gain favorable vibration and acoustic behavior of vehicles. The body structure is the most significant transfer path for road-excited and engine-excited vibrations. The body panel vibrations are then radiated into the vehicle cavity, where they are perceived as audible noise. Apart from the audible noise, which is transferred into the cavity, structural vibrations of the body are perceived as an annoyance as well. AEG Product Design and engineering solutions have a dedicated and focused NVH team with core competency in solving complicated design problems pertaining to automotive and aerospace applications with HPC (High Performance Computing : SGI-Altix/16 GB RAM/1500 GB …
