Abstract
This paper proposes a new concept of a deployable structure which is required for transportation and construction of space structures such as a Solar Power Satellite. The objective of the present study is to investigate the possibility of a deployment system which enhances its deployment reliability in space. This paper presents two types of variations of our previously proposed 'linked panel unit' and their rigid body motions. The first one is a multi-degree-of-freedom system of the 'linked panel units' composed of square panels, in which each unit can be deployed independently. The second one is a multi-degree-of-freedom system composed of triangle panels, which can be folded, deployed, and extended two-dimensionally. These new systems may improve the problem of the previous 2D-extended 'linked panel units' that is a single-degree-of-freedom system which has a risk that the deployment cannot be completed by only one malfunction in the structure.
