This master thesis covers the subject of Design of Experiment which is a method of executing experiments or simulations in designed and well planned approaches. The method has been investigated and implemented at a Radar shelter at the Giraffe A4 Radar truck developed by SAAB AB. The thesis was offered by SAAB Surveillance in Gothenburg, Sweden, during the spring of 2018. Design of Experiment was found to be a very powerful method for reducing the number of factors in a large system by executing a number of simulations and evaluating their influence on the studied response. The study of the Radar shelter was done by modelling of a surrogate model of the shelter, parameterization of it and execution of modal and static analyses with designed experiments. The factors studied were dimension of beam components and thicknesses of sheet components. Attempts were made to implement a higher parameterization of the design, involving concept variables and other design changing parameters, but without success. The most demanding and important step to consider during implementation of this method is how the factors of the studied system should be chosen. The factors should be easily adjustable and concrete to enable a parameterisation of these and performing the experiments. The most important responses of the system should be well defined along with other fundamentally important responses to guarantee a robust and reliable outcome from the experimentation. The experimenter should carefully revise the conclusions drawn from the results with respect to the defined experimental setup with boundary conditions and load cases. The results are just as good as the inputs to the experiment.
