Dr. Akbar Farahani, VP of Global Engineering, ETA Introduction The design of automotive body structures is driven by many competing criteria such as lower cost, weight reduction (CO2 reduction, Electric and Battery Electric Vehicle), enhanced multi-disciplinary performance and manufacturability. In addition, the introduction of new manufacturing processes and materials (e.g., AHSS, aluminum, composite) significantly increases …
Neumayer Tekfor develops and produces components and assemblies for the automotive industry. Their product line is divided into transmission, engine, driveline, fastener and chassis. The products developed and produced are manufactured with different kind of methods, mainly warm/cold forming and ring/wedge rolling. To reach all the requirements needed, Neumayer utilized Simufact.forming to perform preliminary analysis, …
Crankshafts for large diesel engines that are used in container ships are usually forged in middle and small series. Because every crankshaft has specific features, their manufacturing and design is a challenge. This is where the forming simulation comes into play. Wildauer Schmiedewerke GmbH is one of the few companies that is able to manufacture …
Aircraft loads are the forces and moments applied to the airplane structural components to establish the required strength level of the complete airplane. These loadings may be caused by air pressure, inertia forces or ground reactions during take offs and landings. Determining design loads involves a full aircraft analysis of the air pressure and inertia …
Omni-Lite Industries is an advanced material company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material.
The initial tool design was completed and reviewed using the Simufact.forming simulation. Upon initial review, everything seemed to be acceptable, with the exception of the volume of material in the flange of the part. The second station trap extrusion die radius was then reduced in order to accommodate the material volume requirements.
The role of fluid dynamics simulation in the design and development of various products has recently undergone what is arguably a paradigm shift due to the ability to simulate unusually complicated, multi-component, hydraulics flow circuits using three dimensional (3D) computational fluid dynamics (CFD) models. The example shows a lubrication system model (developed using the Simerics-Sys / PumpLinx CFD software) for a 16 cylinder reciprocating internal combustion engine. This represents an advance in system-level modeling of hydraulic fluid networks over the current state of the art which is a blend of zero and one-dimensional models. This also represents continued progress in the role of CFD from the traditional component level modeling to system level modeling. System level modeling provides insight into interactions between components. Finally, it is equally important that model setup and run times are reasonable relative to development time scales.
