407 非拘束宇宙構造物の静的有限要素解析(計算力学と数値シミュレーション)
詳細
This paper is intended to established the general method to solve static and elastic problems of unconstrained space structures using Finite Element Method. The discrete governing equations can not be solved because the stiffness matrix of free-free bodys is singular. The modified equations is obtained from reducing the dynamic equilibrium equations under the constant velocity motion and the Rayleigh damping proportional to the mass matrix. The validity of computational method is confirmed by comparison of analytical results for simple framed and plate/shell structures.
