Mar 2012 This paper reports the results of numerical optimization analyses aimed at increasing the energetic efficiency of a GDI engine equipped with a high pressure multi-hole injector under both single and double injection events. In moderate-load moderate-speed lean conditions, the single or double injection synchronization in the working cycle is done through a procedure that couples a 3D numerical model of the in-cylinder processes with modeFRONTIER. read on Energy efficiency of a gasoline direct injection engine

Jan 2012 In past decades the simulation results of vehicle impacts have reached high confidence levels. However, impact simulation remains computationally expensive, even though it is commonly used. Surrogate model or response surface based design optimization has been widely adopted as a common process in automotive industry, as large-scale, high fidelity models are often required. read on A method for selecting surrogate models in crashworthiness optimization

Sep 2011 Wearing a child restraint system (CRS) greatly improves the crash-safety of children and reduces their fatal or severe injuries in traffic accidents. However, since the number of children’s injuries in traffic accidents hasn’t decreased, much further CRS improvement is required. This study clarifies the effect of active harness control and improves CRS by optimizing its controller parameters. read on Active Control of Child Restraint System in Frontal Crash

May 2011 The social demands for low cost and fuel efficient vehicles are increasing. At the same time the engine power is increasing and customer expectations of reliability and NVH levels are increasing. To meet all the requirements, engineers are challenged to design light weight parts with higher performance. read on CAE Methodology for Optimizing NVH

May 2011 The hysteretic loss associated with cyclic shear in the elastomeric shear layer is one of the prevailing concerns for the development of a low rolling loss non-pneumatic wheel. We propose to eliminate the hysteretic losses associated with the elastomeric shear layer and thus, reduce the corresponding rolling resistance by using linear elastic materials which are inherently non-hysteretic. read on Non-Pneumatic Wheels and Low Rolling Resistance

The work consisted of analysing the aerodynamic and structural effects applied to a rear wing of a Formula-type vehicle. In order to accomplish this goal it is necessary to optimize bearing in mind of both disciplines and employing new coupling capacities featured in the software, as well as the versatile control and advanced statistical tools provided by modeFRONTIER. read on Multidisciplinary Robust Optimization of a F1 Rear Wing

125cc motorbike racing is among the most demanding competitions from all possible standpoints. The improvements are obtained by focusing all efforts on detailed aerodynamic and weight reduction analyses in order to make the most of the poor engine power and the reduced weight in the bends. read on Aerodynamic optimization of a 125 cc motorbike rear cowl

The development of a rear wing for a Formula One single-seater is a very complex job. In order to reduce the amount of resources employed in the simulation runs, we decided in the first place to perform the computation solely on the rear portion of the single-seater. In order to manage the simulation runs and accomplish the optimization, we resorted to modeFRONTIER read on Aerodynamic optimization of a Formula One rear wing

Dec 2009 modeFRONTIER was used to automate the robustness study using LS-DYNA and
METApost. In order to save computational cost, a submodel instead of a full vehiclemodel
was used for the robustness and metamodel evaluations. read on Robust Design Optimization of a Bumper System at Volvo Cars

The use of genetic algorithms (GAs) is enjoying ever-increasing popularity among engineers and designers as a way of optimizing their products and processes. One of the major advantages of such techniques is that they allow true multiobjective optimization (where the objectives are kept separate throughout the optimization process, rather than being collapsed into a single, weighted objective function from the beginning). read on MultiObjective Optimization in Engine Design

Oct 2005 Internal Combustion Engine (IC-Engine) efficiency and emission characteristics are at great extent, governed by the details of the intake port-combustion chamber arrangement. In this context, the discharge coefficient and swirl/tumble numbers, are commonly used to characterize the intake port with respect to the volumetric efficiency and, at least partly, to the combustion of both diesel and gasoline engines. read on IC-Engine Intake Port Optimization

Oct 2000 Thanks to the multi Objective capabilities of FRONTIER, it was possible to
optimize simultaneously comfort and handling manoeuvres. Both options of coupling
Adams directly and Adams Insight module have been successfully verified. Multiple
runs with different manoeuvres are taken into account into the definition of the design
