The objective of the present study is to investigate the dynamic motion of a deployable structure, which is composed of a scissors mechanism assumed to be deployed in space with a self-balancing moment by actuators. For this purpose, the present paper focuses on how to calculate the dynamic motion of deployment of the scissors mechanism in space with a self-balancing moment, in consideration of its mass and rotational friction around the joints, and showing its numerical results. The present paper also checks the stress and deflection of the frame, as a problem of the structural analysis of an unstable structure without outer boundaries.
The objective of the present study is to reveal a dynamic calculation method for a deployable scissor structure in space as an unstable structure without boundaries, by generalizing its dynamic modeling to predict the relationship between its deployment motion and input moment generated by an actuator. The purpose is to study the construction process of space structures such as a solar power satellite in future. Whereas our previous study demonstrated a specific derivation sequence of a dominant equation of a scissors unit, the present paper shows the generalized derivation sequence and its numerical calculation examples of more extended analysis models.
The objective of the present paper is to propose a twodimensional extension method for our previously proposed deployable 'linked panel unit' for construction of huge flat space-structures such as a solar power satellite. In our previous study, we proposed a one-directional extension method of the 'linked panel unit'. However, its two-dimensional deployment was assumed to be feasible with an additional mast. To address that issue, the present paper proposes a new 2D-extension method of the 'linked pane unit' without using an additional mast, and suggests it for realization of a solar power satellite as a huge flat construction in space.
