Abstract [en]

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties. The methodology should be seen as a guide anda source of information to enable an iterative approach with FE-analysis, which isthe basis of simulation-driven design. The iterative process of simulation drivendesign, which can lead to reduced lead times and cost savings in the designprocess.The work was carried out by three students from the mechanical engineeringprogram between December 2014 and May 2015. Because of the scale of theproject, it has been carried out by a total of three students with individual focusareas.The work has followed a self-developed method and the project began withtheoretical studies of the topic to get an understanding of what has been done andwhat research in simulation driven design. Then conducted an empirical study onthe Saab Dynamics in Linköping, in order to increase understanding of how thedesign process looks like. Meanwhile, sustainable development and ethicalaspects has been taken into account.Much time has been devoted to investigate the possibilities and limitations of 3DExperience, which is Dassault Systèmes latest platform for 3D modelling- andsimulation software. 3D Experience is the software, the methodology is based on.This thesis has resulted in a methodology for simulating at the designer level thatthe project team in consultation with the supervisor at Saab Dynamics managed toadapt to the company's requirements.
