What you will be a part of

Surveillance provides efficient solutions for safety and security, for surveillance and decision support, and for threat detection and protection. The portfolio covers airborne, ground-based and naval radar, electronic warfare, combat systems and C4I solutions, and traffic management systems.

The thesis work will be performed on the section of environmental analysis. The section of environmental analysis is responsible for environmental engineering analysis within structural analysis, thermal analysis and material analysis. Our mission is to be a support function to ensure safe and reliable products regarding electronics, mechanics and system structures.

The section is involved from early concept design through defining necessary requirements, perform detail design and structural analysis and finally verify the final Product. 

The CAE software tools we use are the HyperWorks package from Altair (HyperMesh, HyperView, HyperStudy, OptiStruct) and MSC Patran/Nastran/Adams for structural analysis, while for the thermal/CFD analysis we use ICEPAK and Fluent.

Your role

Optimization of a complex system is very time consuming due to large amount of parameters (or design variables). Design of Experiments (DOE) can be used as parameter screening to determine which factors are most influential to the design goals. The initial screening will discard parameters which do not influence the system, hence reduce the number of parameters and calculation times. 

This thesis work is a further work of a thesis work carried out on the section during spring 2018. The previous work evaluated the theoretical models for design of experiments (DOE) and perform parameter screening. This thesis work is to implement the theories for a higher level optimization of a shelter for a radar system, i.e. optimization in a system level with different design concept. 

The objective of a DOE study is to understand how changes to the parameters of a model influence its performance. In such a study, effects and interactions of the design variables of the model can be studied. DOE is widely used in research and product development, where a large proportion of the resources go to solving optimization problems. DOE study can determine which factors are most influential on the responses, will provide a global understanding of the complete system, hence reduce the number of parameters and simulations. Performing DOE study in the initial design phase will improve the quality and saving design cost.

Your skills and experience

You are probably today studying mechanical engineering, applied physics or equivalent. It is natural for you to work in a team toward a common goal.

Saab is a global defence and security company operating in the fields of air, land and naval defence, civil security and commercial aeronautics. We number 15,500 employees and have operations on all continents. Technologically we are leaders in many areas, and one-fifth of our earnings are spent on research and development.

Saab is also a company with opportunities. A company where we see diversity as an asset and where you have both considerable responsibility and good opportunities for advancing in your career. But also a company that respects each person’s needs for a rewarding life beyond work.
