Formulation and experimental validation of flexible structure for space application which is subjected to large deformation.

以二维柔性梁作为空间柔性展开结构的基本要素，建立了其数学模型。基于绝对节点坐标法（ANCF）建立数学模型，并考虑了传统的内粘度模型和空气阻力模型。动态刚化效应是一种具有大的旋转和变形的运动，这是因为部署结构经常经历这样的效果。实验验证表明，传统的内粘度模型和空气阻力模型具有较好的一致性。

Mathematical model is constructed for a 2-dimensional flexible beam as elemental factor of flexible deployment structure for space applications. The mathematical model is constructed based on Absolute Nodal Coordinate Formulation (ANCF) method and conventional internal viscosity model and proposed air drag force model are considered in the formulation. A dynamic stiffening effect which is a motion with large rotation and deformation is focused on because deployment structures often experience such an effect. Experimental validations about conventional internal viscosity model and air drag force model show good correspondences.
