Optimisation methodologies applied to the design of a gas turbine cooling system

Design optimization techniques are a new frontier in engineering planning. Usually designers use “cut and try” methods in developing their projects, taking advantage of their Company’s Databases and internal know-how. Optimization algorithms can join this system and give a relevant improvement to the development time and design quality. In its R&D department , AVIO Group has began some projects in order to test the capabilities of 
modeFRONTIER®, when coupled with its own software and methodologies and applied to turbo machinery problems.

Automated Design Optimization For A Diesel Combustion Concept Based On CFD Flow Analyses

The improvement of fuel consumption and emission behavior is a main challenge of combustion engine development today. Further optimization of mixture formation and combustion process are needed for diesel as well as for gasoline engines. In addition the strong impact of the intake port flow and the incylinder flow motion is widely known. To get detailed information rapidly FEV uses 3-D flow simulation (CFD) for the optimization of port and piston bowl CAD-layout.

Improving a virtualrace car performance using MSC.ADAMS-Car-MotorSports and modeFrontier

The application of virtual prototyping tools to reduce product development cycle times has been the initiative of every successful auto manufacturer in the current economy.For small, high performance or race vehicle niche manufacturers, the integration of virtual prototyping tools is necessary if it wishes to survive in ultra competitive lean automotive manufacturing arena.

Robust Design of An Inflatable Knee Bolster

This paper investigates an integrated robust design approach for occupant restraint system by taking advantages of design of experiments, variable screening, stochastic meta-modeling, and genetic algorithm. An inflatable knee bolster design is used as an example to demonstrate the methodology; however, the proposed method is applicable for all occupant restraint system design problems.

Design optimization of a composite car body

The presentation focuses on the design optimization of a composite car body

Multi-objective optimization of a complex water distribution network

The activity presented in this proceeding has been divided into three phases: The first phase focuses on the position on the network of the minimum number of valves, in common with all the scenarios; the second phase deals with the determination of the optimum opening degree of the positioned valves, for every scenery and finally the third phase, which deals with the determination of the found solution robustness in respect of pipes roughness and node demands.

Stirling engine optimization based on Schmidt and adiabatic analyses

The proceeding, presented at the user meeting 2006 by the University of Modena and Reggio Emilia, focuses on the stirling engine optimization based on Schmidt and adiabatic analyses

Prediction of Parameters of Vehicle Dynamics Simulation Model using modeFRONTIER

Vehicle Dynamics Simulation is widely applied to many stages of vehicle development, accuracy of the simulation is strictly required. Since accurate vehicle dynamics simulation requires correct vehicle parameter value, but they are hardly be obtained in many cases, during the stages of the vehicle development system suppliers are usually in such circumstances due to measurement facilities / confidentiality. However, running vehicle behavior can be measured and logged as chronological data. Since “Data to be compared” are not simple index but chronological curve, decision criteria (good or bad etc.) they tend to be subjective, thus hard to be consistent. The procedure to predict reasonable value of each parameter could be defined only by well experienced engineer in Vehicle Dynamics Simulation field, skillful engineer has to repeat “Trial and Error”,this work to be done isn’t creative, thus it is really wasting time and money.

Robust Design Optimisation using Linux Networx cluster

This presentation is a robust design example that proves the efficiency of Linux cluster and queuing system combined with the parallel capacities of modeFRONTIER. A problem that would have required months of computations using a single CPU machine, has been solved in three days using a cluster of 64 CPUs.

Introduction of modeFRONTIER Application Examples in Japan

Nowadays in Japan, “Optimization” is widely recognized and accepted as a necessary Technology for improving Development Efficiency. Furthermore modeFRONTIER is getting ?rm position / market share of universal Optimization Tool in Japan, also non-CAE Engineers have started using modeFRONTIER for approximating Response Space and Design Optimization using the RSM.
