Abstract:

Determination of redundant tension distribution for completely restrained positioning mechanism is transformed into a polynomial formulation extreme value problem in the convex feasible domain in this paper; and the real-time and continuous indices for measuring cable tension optimization solutions is also presented. A typical cable tension optimal distribution of the CDPCR is determined in order to provide an insight into the problem, so that the real-time and continuity of several tension optimal indices are compared and analyzed. Furthermore, concrete suggestions of index selection are given.

Key words: cable-driven parallel manipulator, camera robot, redundant actuation, optimization of driving force, real-time, continuity
