Abstract:

In the article is presented a new design of a closed-chain deployable cone system with V-folding rods, which is an evolution of prior designs demonstrated previously, and are considered the structural schemes of transformable systems and their block diagrams. Structural analysis is carried out taking into account the character of structural components (elements). Relative degrees of mobility of systems are established, which control the deployment of systems until it reaches the design position. A law of the process of unfolding is established in conformity with geometrical and kinematic specifications, taking into consideration the degree of regulation. A methodology is proposed for the kinematic analysis of the system that takes into account its structural peculiar properties. The geometry of the block diagram is discussed and the kinematic analysis of the cone transformable system is carried out – the obtained data allow one to determine the function of position of the whole system and to evaluate the process of its deployment.

Keywords: deployable system; geometric constraint; kinematic analysis.
