Handling the Complexity of Mechatronic System Design

Two design projects highlight how ABB Group leverages optimization-based development to handle the complexity that automation and control systems entail and to maximize mechatronic product performance, meet reliability demands and ease overall environmental impact.

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

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. 

Flutter Based Aeroelastic Optimization of an Aircraft Wing with Analytical Approach

This paper presents a flutter prediction methodology for three dimensional wing and wing/store configurations by using the well-known Goland and AGARD 445.6 aeroelastic wing models. Flutter analysis of the AGARD 445.6 wing is performed with an in-house flutter solution code coupled with the optimization software, modeFRONTIER. 

Design optimization of a 3-unit satellite de-orbiting mechanism

The main goal of the present work is to design an efficient de-orbiting system providing the shortest de-orbiting time with an easily deployed mechanism. The de-orbiting mechanism of interest is 3USAT from the Space Systems Design and Testing Laboratory (SSDTL) of Istanbul Technical University. An in-house code developed for the calculation of minimum aerodynamic drag force and spring moment is coupled with modeFRONTIER to perform multi-objective design optimization of the de-orbiting mechanism. 

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. 

Optimization for Train Energy Performance

This study aims to find solutions to lowering energy consumption in train transportation. The optimization of timetables and driving styles are both investigated in this paper. Softwares Train Energy Performance (TEP) and modeFRONTIER are coupled to find energy saving solutions for trains.

Optimization as an innovative design approach to improve the performances and the functionalities of mechatronic devices

This paper describes an optimization process for both structure and parameters of a mechatronic device, specifically a laser cutter. A strategy based on the evolutionary case-based design approach has been developed using modeFRONTIER. The design approach is applied to a practical cast study which shows how the chosen methodology can be used as a design method

Fuel Consumption Minimization Procedure of Sail-assisted Motor Vessel based on a Systematic Meshing of the Explored Area

This paper presents a complete route optimization procedure for sail-assisted motor vessel routing using deterministic medium range weather forecast and a parametric model of ship performances. A method for spatial and temporal generation of route variants based on a generic and automatic meshing method has shown optimal results. 

Evaluation of Railway Vehicle Car Body Fatigue Life and Durability using Multi-disciplinary Analysis Method

An integrated fatigue life and durability evaluation method based on multibody dynamics simulation (MBS) and finite element analysis for a locomotive car body is presented. A multi-disciplinary optimization algorithm is developed to handle the conflicting requirements of lightweight and good fatigue resistant car body structure designs.
