碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 90 === Analysis of the frangibility of airport approach lighting towers using both full-scale impact tests and computer simulation were performed in order to develop a better understanding of buckling and failure mode of he tower when struck by a representative aircraft. These data were necessary for the development of simplified requirements and test methods for the design of frangible structures, in order to minimize the impact hazard to aircraft. This thesis describes the model developed to simulate the impact properties of the tower using the LS-DYNA3D finite element analysis software. Three different velocities 50、80 and 140km/hr were used in combination with two different orientations of the tower to cause impact at the apex and on the side of the triangular cross section tower. The results obtained using this simulation were compared to the experimental results from full-scale tests. In addition, the tower dynamic behavior was compared to the high-speed video imagery to confirm failure mode predictions.
