Abstract

In this article, the mechanism of a parallel structure with six degrees of freedom with a circular guide and consisting of three kinematic chains is investigated. The paper considers the problem of structural synthesis, solves the problem of kinematic analysis, and proposes an algorithm for determining and studying the working area. The working area of the mechanism is six-dimensional and difficult to visualize. As an alternative to the wellknown approaches to solving this problem, a technique for numerical scanning over discrete grid points is proposed. Grid dimensions are assigned at the initial design stage and can be adjusted depending on the problem statement, while at each grid point three absolute angular coordinates are scanned with a certain step.
