Program Displacement Tracing of Executive Devices by the Manipulator Drives of Parallel-Sequential Structures

Abstract

Synthesis methods for program displacements are developed for executive cylinders of the manipulator of a parallel-sequential structure, that ensure implementation of the required trajectories of the executive device of a manipulator. Program displacements of executive cylinders are interpolated by a finite collection of third-order and fourth-order splines. At each point of the trajectory of the executive device, the manipulator configuration is determined by resolving an optimization problem with the minimum condition of the generalized energy criterion.
