| Research Abstract |
Recently, a large-scale and high precision space structural system is required. A smart structural system that integrates sensors and actuators into the structure is acandidate of such high precision space structures. In designing such a high precisionspace structure, uncertainties on applied load or material properties should be considered. Such uncertainties often have spatially-varied distributions. For the purpose, we developed a new robust topology optimization approach considering such uncertainty by adopting the stationary stochastic process. Since the stochastic process model can reduce the number of random parameters, the computational efficient design approach is achieved.
