Outline of Final Research Achievements |
We formulated a simultaneous optimization problem on one of the hopeful large space membrane structures which has membrane-boom elements. Wrinkles with strong nonlinearity, and structural features ever has been separately considered. Focusing on that point, we introduced the combination of satisficing trade-off method and heuristic search, and then, its possibility was shown to explore an optimum design which never can be found by the linear summation objectives. We looked at structural significance of an obtained model, and showed the effects of a series of proposing design and analysis method. Along with that, we examined the contributions in detail about mechanisms of structural members like cables onto structural characteristics, and proposed the future standard model of a membrane- boom structure. Additionally, we proposed the 3D membrane-boom structure, and mentioned its potentials.
