Abstract
In this paper, we presents how to reduce an analysis time for a dynamics of large-sized flexible space structure. Large space structure, such as Space Solar Power System is planned in near future, however these plans have a problem caused by a large flexibility of space structure. By conventional way, ground experiment and structural analysis are conducted to verify a possibility. It is difficult to conventional way to future large space structure because large flexible structures are suffered many factor and cause errors. We have been studying about online dynamics simulator to solve that problem in operation phase. One of the problem of developing online simulator is simulation time increased by a complexity of dynamics model. In conventional model, non-linearity is existed in a material property and structural property. Linearization is applied to conventional model to reduce a simulation time. As a result, simulation time is reduced with enough simulation accuracy.
