In this paper, a deployable ring mechanism capable of supporting a large flexible cable net antenna reflector is presented.
The ring mechanism has very high deploy/fold ratio, which is suitable for building large scale satellite deployable antenna.
Two types of driving mode for the deployable ring mechanism including cable driven and torsion spring driven are studied, and the high rigidity driving joints are designed.
In order to meet the missions, this paper presents a kind of novel single mobility deployable ring mechanism based on a set of planar six-bar linkages.
But with the variable angle screen, pocketable form factor, and unique control ring mechanism, it's a winner based on my early initial tests, especially for those looking for something with better IQ than their smartphone, but with a lot of the same features and similar portability, too.
A modified deployment motion planning method based on force-control is proposed, and the relationships between control force and motion are ascertained and verified by a prototype of the ring mechanism.
The mobile assembly of the ring structure and synchronous movement compatibility conditions are investigated, then the synchronization movement of the six-bar linkage modules can be realized by using close-loop cable and dual slider-crank mechanisms, which ensure the single mobility of the whole ring mechanism.
This behavior is enabled by the RING mechanism, whereby the resonant properties of interneurons introduce lower and upper bounds on the period of the oscillation cycle.
Thus, the RING mechanism can lead to network properties that are very different from what has been shown for other systems and this further underscores the importance of membrane properties in modulating oscillatory behavior of networks.
In addition, to check whether the identified RING mechanism is not an artifact due to the different models of interneuron but is indeed relying on membrane resonance, we kept the interneuron model unchanged (i.e. Izhikevich type) but manipulated the parameters of the Izhikevich model from resonator to regular-spiking (RS).
