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。

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.

DSHplus and AcuSolve - Fluid Power System Simulation Hand in Hand
This was a 2013 European ATC presentation given by Dr. Heiko Baum from FLUIDON Gesellschaft für Fluidtechnik mbH. Today the dynamic behavior of complex fluid power systems is typically simulated with 1D system simulation programs such as DSHplus. But, if accuracy requires modeling details at component level this technique comes to its limits. The representation of pressure losses of complex flow channel geometries, such as the bores in hydraulic manifold of heavy machinery or the customized pipe layouts in automotive applications or aerospace applications, cannot be achieved with a series connection of 1D system components.

To avoid such troubles and increase the accuracy of the safety analysis, a process has been developed in HyperCrash based on RADIOSS simulations.

Stamping Process Integration of Composites in Crash Analysis
This was a 2013 European ATC presentation given by Cécile DEMAIN from Solvay Engineering Plastics. Thermoplastic composites (TPC) developed by Solvay Engineering plastics are composites based on polyamide 6 or 6.6 as a matrix and can be reinforced with glass fibers or carbon fibers. The two main interests vs. TPC. thermosetting composites are cycle time and recyclability. The development of TPC PA66 or short fiber hybrid structures / TPC PA66 is today's challenge.

Humanetics Anthropomorphic Test Device News and Radioss Model Developments
This was a 2013 European ATC presentation given by Robert Kant from Humanetics Europe GmbH. Main stream finite element models of ATDs see continuous improvements to keep the models up-to-date to the latest hardware, latest solver codes and to make them more predictive. New validation tests are continuously being designed to gain more insight in the understanding of the ATD. Furthermore, more knowledge is obtained on variability which plays a role in the attempt to make highly reliable models.

Impact of a new regulation for Child Restraint Systems on the crash simulation
This was a 2013 European ATC presentation given by François Renaudin and Sylvaine Pormente from DOREL. Injuries to children involved in car collisions can be significantly reduced if they use a suitable car seat. All Child Restraint Systems CRS (or car seats) sold in the EU must conform to the United Nations Regulation. A new regulation on CRS, known as the “I-Size regulation”, will be adopted in 2013 by the UNECE.

Multidisciplinary Optimisation of Business Jet MED Hinge for Production by Additive Manufacturing
This was a 2013 European ATC presentation given by Martin Muir, Jonathan Meyer, and Alex Diskin from European Aeronautic Defence and Space Company (EADS). Additive Manufacturing (AM) using Powder Bed Fusion (PBF) processes is a novel and rapidly expanding manufacturing field which eliminates many conventional constraints from the manufacturing process. With the reduction of design inhibitors such as tool paths, AM becomes an ideal process for the fabrication of topology optimised (TO) structural designs.
