Trim material is studied for the optimization of vehicle acoustics in order to increase quality in the automotive industry. Here the combination of modeFRONTIER and Actran result in an excellent numerical representation of complex porous material.

Lightweight Multidisciplinary Optimization for Vehicle Part Design

This presentation from the Ford Motor Company demonstrates the advantages of multidisciplinary optimization with the aim of achieving lightweight design. The integration of softwares modeFRONTIER and CATIA makes for quick and easy optimization with the optimal result of robust, lightweight designs. This study demonstrates an optimization process of a motor vehicle chassis part.

Multidisciplinary Design Optimization of Vehicle Weight Reduction

In this study from ESTECO North America, a six-step MDO process is illustrated by solving a 2001 Taurus weight reduction problem with two formulations AAO and CO. The chosen optimization platform is modeFRONTIER plus SOMO. Conclusions show the advantages to using AAO methodology in MDO.

Design of a Meta-Material with Targeted Nonlinear Deformation Response

This thesis aims to demonstrate the possibility of designing a meta-material to match a nonlinear deformation response. Application of this method was successful in generating a meta-material to meet the response of the rubber pad in an M1 Abrams tank. The optimization method using modeFRONTIER can serve as a framework for future designers to develop meta-materials for nonlinear targeted responses

Three-dimensional numerical analysis of diesel combustion under cold ambient conditions

The purpose of this study was to clarify the relationship between the air–fuel mixture distribution and various multiple injection patterns based on both experiments and 3D computational fluid dynamics (CFD) simulations. Special attention was paid to the region near the glow plug under low-temperature conditions. The test engine was a four-cylinder direct injection diesel engine with a compression ratio of 15.0:1. The constants of the shell model were optimized using a genetic algorithm in modeFRONTIER.

Thermal Analysis of a Diesel Piston and Cylinder Liner using the Inverse Heat Conduction Method

This Master’s thesis developed a thermal analysis model of a diesel piston that is used in Volvo Cars engines, which enhances the possibilities to determine the complete thermal loads of the car engine and can be used as a boundary condition when performing combustion CFD-simulation. 

The Product Innovative Design Methodology Integrating Reverse Engineering with Optimization - A Case Study on Automotive Styling

Although many CAD systems exist, in the initial design phase of a product, it’s still a challenge to obtain a shape that meets aesthetic and physical performance requirements simultaneously. An innovative design methodology integrating reverse engineering (RE) with optimization is presented to settle this problem. RE is used to convert a clay model to a spline-based surface model. The final solution is found through a multi-objective genetic algorithm from modeFRONTIER.

Sensitivity analysis of CFD method with modeFRONTIER

In this thesis, the development of a new defroster duct system prototype is carried out. The suitability of using modeFRONTIER for sensitivity analysis has been investigated coupling ANSYS/FLUENT as a main solver. To study the numerical solution of the windscreen de-icing process, a computational fluid dynamics (CFD) method has been used. 

Rapid deployment of remote laser welding processes in automotive assembly systems

Remote laser welding (RLW) is emerging as a powerful and promising joining technology (one of the KETs) in vehicle manufacturing. However, potentials of RLW are currently underexploited, mainly due to challenges in system and process design, part variation, fixturing, offline programming, as well as process monitoring and control. The RLW Navigator framework was applied in a detailed automotive pilot study which yielded promising results.

Influence of Body Stiffness on Vehicle Dynamics Characteristics in Passenger Cars

This study aims to analyze how vehicle dynamics are affected by local and global car body stiffness. The influence of these parameters in vehicle handling, steering and ride attributes are examined through CAE analysis tools and compared to results from physical tests. The software used for the graphical visualization and correlation of large data sets of results from the performed DOE is modeFRONTIER.
