Nonlinear Modeling and Optimal Initial Profile Solution for Deployable Mesh Reflectors

Coupled Elastic-Thermal Dynamics of Deployable Mesh Reflectors

“…Although it has been a challenge to increase both size and surface accuracy at the same time, the previous studies [5,6] have suggested that the active control on the shape of structure should be introduced in the development of deployable space reflectors. To ultimately develop an active surface control technique, the authors' previous works have delivered an optimal design of initial profile and a nonlinear static model of mesh reflectors [7,8]. The work in this paper is the continued research following the previous paper [9].…”

A Nonlinear Dynamic Model and Free Vibration Analysis of Deployable Mesh Reflectors

“…To develop an active surface control technique, a control-orientated dynamic model of deployable mesh reflectors is necessary. Following the authors' previous effort on the design of initial profile of mesh reflectors [9,10], this paper presents a method to build up a control-orientated dynamic model. The model is based on the structural dynamic theories [11 -14], and should be ready for the design of feedback surface control laws in future research.…”
