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.
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.
