Faurecia Emissions Control Technologies enhances development processes with HyperWorks
Within the development of its exhaust systems Faurecia Emission Control Technologies in Germany uses HyperWorks for meshing, linear FE-analysis, optimization and post processing. For the automotive industry it is very important to reach a reduction of CO2
greenhouse gases in vehicles that are newly developed. This involves reducing fuel consumption and in case of Faurecia Emission Controls lightening the exhaust system. In the time frame of the last five years, Faurecia has reduced the average weight of exhaust systems by 20%. The group has achieved this by re-designing the system’s architecture and
using new materials, such as building fabricated manifolds instead of cast iron. Faurecia uses HyperWorks to develop and analyze single components of the exhaust system as well as the entire system behavior. The areas in which HyperWorks is used are:
• Complete system durability
• Component shape, size, geometry and position optimization
• Noise Vibration Harshness
• Catalytic converters, diesel particle filter
• Lightweight fabricated manifold

Evolving Trends in the Structural Optimization of Aircraft Gas Turbine Engines
Brian Cottrell, Chief Engineer of Structures, Honeywell Aerospace

The history of aircraft gas turbine engine design generally has not included significant optimization of the structural layout of engines. This optimization gap has been driven by the pace of engine layout during the concept development phase and by the extreme complexity of the problem. Therefore the initial selection of the structural system concept has tended to be anchored in experience and in simple parametric trade studies seeking to provide a sound configuration from the perspectives of strength, weight, cost, and modularity.

Investigating Aeroelastic Performance of Multi-MegaWatt Wind Turbine Rotors Using CFD
Recent trends in wind power technology are focusing on increasing power output through an increase in rotor diameter. As the rotor diameter
increases, aeroelastic effects become increasingly important in the design of an efficient blade. A detailed understanding of the fluid elastic
coupling can lead to improved designs; yielding more power, reduced maintenance, and ultimately leading to an overall reduction in the cost
of electricity. In this work, a high fidelity Computational Fluid Dynamics (CFD) methodology is presented for performing fully coupled Fluid-
Structure Interaction (FSI) simulations of wind turbine blades and rotors using a commercially available flow solver, AcuSolve. We demonstrate
the technique using a 13.2 MW blade design.


Faster Design Changes with HyperWorks’ Morphing Technology
In the development of engine components PSA determines the lifetime of the intake manifold with a complex thermo mechanical calculation. Since the development process is distributed between PSA itself and a supplier, a design change of the intake manifold takes three weeks to be evaluated. For the supplier it has always been hard to correctly interpret the design improvements suggested by the PSA CAE engineers. Due to the three weeks of time, the iteration between OEM and
supplier takes, and because the overall development time is limited, the process just allowed a few design changes. Therefore the design of the manifold can become a critical task in the
engine development. With HyperWorks’ morphing technology (HyperMorph) it is possible to quickly implement design changes and hence to avoid intermediate CAD changes. With this process, only a single final CAD revision is needed when all improvements have been done. The new
workflow with HyperWorks’ morphing technology allows for a much faster evaluation cycle of two days instead of three weeks with the former process.

在发动机部件的开发中,PSA确定进气歧管复杂的热寿命计算。 由于开发过程在PSA自身和供应商之间是分布式,一个进气歧管的设计变更的评估需要三周。对于供应商来说,一直很难正确诠释PSA CAE工程师提出的设计改进建议。由于OEM和供应商之间的迭代需要三周时间,而整体开发的时间是有限的,设计流程中就只限少量设计变更。因此,该歧管的设计可以成为发动机开发的关键任务。HyperWorks的网格变形技术(HyperMorph)可以快速实现设计的变化,从而避免中间CAD的变化。在这个过程中,只有一个单一的最终CAD需要修改,而所有改进都已完成。HyperWorks的网格变形技术的新流程实现了更快的评估周期,从原先的三周缩短到两天。

Improved Mechanical Performance and Reduced Cost of a Solar Panel System with HyperWorks
HyperWorks proved to be exceptionally valuable in Luxon’s work for a major producer of a large-scale industrial panel system, which measures approximately 50 x 70 feet and rotates to track the sun. The company had a system in production but sought to lower the cost of manufacturing. Additionally, Luxon’s customer wanted to expand the geographic locations where the system could be installed successfully, so it asked Luxon to develop
a more robust support structure to ensure that the system would survive the seismic,
wind and snow loading that the product was likely to encounter in various parts of the world.


Consideration of uncertainties in forming simulation using HyperWorks
This was a 2013 European ATC presentation given by Markus Reinert from DTE Werkzeugtechnik GmbH & Co. KG. In the automotive industry, the lightweight is an increasingly important issue. This leads to the increased use of high strength steels and aluminum. These materials decrease the process capability of forming of many automotive components than conventional materials. It becomes more difficult to predict the feasibility of CAE methods.

Prediction of warpage in welded assemblies
This was a 2013 European ATC presentation given by Dr. Amin Sedighiamri from SABIC. Long glass fiber reinforced polypropylene (PP-LGF) is a material often used in semi-structural automotive components, such as front-end module carriers, door modules, dashboard carriers and hatch back doors. Main process for the production of these parts is injection molding, which generates complex glass fibre length and orientation distributions during processing.

Sequentially Cold Forming Simulation of Complex Shaped Heavy Plates
This was a 2013 European ATC presentation given by Dipl.-Ing. Steffen Garke from Universität Rostock. Swept lines and derived double curved shapes are not only satisfying an esthetic concept, particularly in ship and offshore structure their implementation is essential for certain aspects like drag of the hull. In ship building it is often about one of a kind or miniseries manufacturing. Therefore the demand for a flexible production process for complex formed plates is at hand.

Process Simulation of Tube Stamping on HyperWorks Platform
This was a 2013 European ATC presentation given by Metin ÇALLI from Coskunöz Metal Form . The main targets of automotive industry can been represented by (a) the reduction of the vehicles environmental impact (pollutions, fuel consumption, CO2 emission), (b) the increase of safety (impact absorption performance, crash resistance, pedestrian safety, etc.), and (c) the improved accuracy and quality for easier, cheaper and more reliable joining and assembly of final components.

Fatigue Due to Random Loadings
This was a 2013 European ATC presentation given by Frédéric Kihm from HBM United Kingdom Limited. Fatigue damage is traditionally determined from time signals of stress or strain using the Rainflow method to extract fatigue cycles. This approach is satisfactory when the damaging events are deterministic and are represented by short data samples of extreme transient loads such as aircraft landing, or automobile potholes.
