Abstract

A novel dynamic equation of a flexible satellite with flexible appendages is developed based on the coupling deformation field, in which the second-order coupling term of axial displacement caused by that of transverse is included. Lagrangian principle and assumed mode method are used to derive the first-order approximate model of the multibody system. Theoretical analysis and numerical simulations show that the coupling term can have significant effect on the dynamic characteristics of the flexible system undergoing large rigid-body motion and the dynamic stiffening is accounted for.
