Design and manufacturing of the all-composite visual display supportstructure of the SIMONA research simulator


The support structure of the visual display system for the research simulator of the International Centre for Simulation,Motion and Navigation (SIMONA) has been designed and built. This paper discusses the design procedure withinwhich two competitive design concepts have been developed. Furthermore, the manufacturing and assembly of theconstruction is highlighted and some tests to components and the assembled structure are described. Finite elementanalyses have been used to make a trade off study to both design concepts. The research simulator is to be used forscientific research in the field of human motion perception, improved simulation techniques, new flight procedures andman-machine interaction. To be able to perform the research desired, the main requirements for the simulator were lowweight and moment of inertia in combination with high rigidity. In this way not only a good response to input controlscould be achieved but also a high first natural frequency for use up to 15 Hz. This high first natural frequency enablesthe reproduction of high frequency vibrations that often accompany the initial response of the actual vehicle.Both design concepts are based on the use of carbon fiber reinforced composites (CFRP) in view of their high specificstrength and stiffness properties. In the first design concept, a truss of carbon fiber reinforced tubes mounts the visualdisplay system to the flight deck. In the second design concept, only a small part of the structure is a space truss, the restof the structure is an assembly of sandwich structures with CFRP facings. As a result of the trade study, the designconcept with the sandwich parts was found most appropriate for further engineering. The most important issues of thedetailed engineering of this concept are discussed.The composite parts of the structure, flat, single and double curved sandwich structures with PVC foam core and CFRepoxy facings, were manufactured using the vacuum infusion technique. The last step in the realization of the simulatorwas assembly of the separate parts with close tolerance bolts to prevent loss of overall stiffness and failure. During theproject, several tests have been carried out. The first test concerned the stiffness of the space truss segments. To preventoverestimation of the rigidity of the space truss in the FEM model, a complete segment of the truss including joints wasbuilt and tested for its rigidity. From the test, an equivalent stiffness is defined for the bar elements in the FEM model.After the assembly was completed, a start has been made with motion tests to check if the performance of the simulatormeets the requirements.......
