Abstract:

In the article is presented a new closed-chain deployable system that at full transformation reaches the conical shape. Individual parts of the system perform the simultaneous motion in the radial direction. A specific feature of the presented in the paper structure is that, as compared with analogous structures, for connecting the sections with one another there is not required application of additional synchronization devices in both belts. The kinematic analysis of the system is carried out for the regulated structural component that would be regarded as a model of the whole system’s kinematics. This mechanism is a differential lever mechanism, the driving elements of which give the possibility to obtain the desired law of motion of a characteristic link. Therefore, is possible to construct the function of the lever mechanism position as well as kinematic functions of transmission.

Keywords: closed-chain deployable system; geometric constraint; kinematic analysis.
