Integrating Design Portal System

As part of the effort to create the new aero space craft, China Aerospace Science and Technology Corporation (CASC) analysed and optimized their design processes. The INTEGRATING DESIGN PORTAL SYSTEM (IDPS) helps to…

Grain Structure Prediction

The control of grain structure, which develops during solidification processes in investment casting of nozzle guide vanes (NGVs), is a key issue for optimization of their mechanical properties. The main objective of…

Thermal calibration and porosity prediction

Investment casting is the only commercially used technique for fabrication of nozzle guide vanes (NGVs), which are one of the most important structural parts of gas turbines. Manufacturing of NGVs has always been a…

Conversion of a Vacuum-Assist Casting to a Conventionally Vented Casting with Casting Simulation

In the current competitive environment, the capability to produce high quality die casting components whilst reducing production cost and development times is a challenge the foundry industry must face up to. Whether it…

Numerical Coupling Models for Complex Systems and Results

The paper gives a status of present electromagnetic (EM) coupling modeling capabilities. Starting from topologically designed systems, it shows how formal rules of the EM topology approach can provide guidance for EM…

Analysis of 24GHz Vehicle Radar Performance with MAZDA

From the standpoint of vehicle appearance, vehicle radar units should be located behind plastic bumpers. Plastic bumpers are made of dielectric material, which causes reflection, scattering, refraction, and diffraction…

Electromagnetic Field Vulnerability of Complex System

In complex systems like ships or airplanes many tasks vital to the function of the system are executed by electronic equipment. Earlier research Camp (2004)– Nitsch (2005) has shown that there are frequency ranges in…

Simulating the Electromagnetic Susceptibility of Automotive Vehicles in collaboration with RENAULT

The tremendous increase in the use of electronic devices in the automotive sector is leading to hard-to-manage EMC situations. The Joint Study presented in this paper is demonstrating the ability of Numerical EMC to be…

Process Chaining Approach With Simulation: From Cast Ingot To Final Properties Of Forged Component

The aim of this study is to evaluate, through FEM software simulation, the quality and properties that can be achieved on a forged component, taking into account results of casting process used to produce ingot . In…

Integration of Coupled Casting and Structure Simulation for Magnesium Die Castings

Simulation is an important tool in the different phases during development. It is used in the early, purely virtual development phase as well as in later production and final test phases, respectively, to analyse and…
