Formulating Assur kinematic chains as projective extensions of Baranov trusses

Abstract: The real roots of the characteristic polynomial of a planar linkage determine its assembly modes. In this work it is shown how the characteristic polynomial of a Baranov truss derived using a distance-base formulation contains all the necessary and sufficient information for solving the position analysis of the Assur kinematic chains resulting from replacing some of its revolute joints by slider joints. This is a relevant result because it avoids the case-by-case treatment that requires new sets of variable el… Show more

“…This is probably the most intuitive and simple approach but, depending on the used formulation, it may be difficult to be accommodated. This chapter is essentially devoted to show how the intrinsic formulations based on distances and oriented areas resulting from bilateration techniques provide a framework within which this idea can be easily applied thus leading to the conclusion that the characteristic polynomials of the Baranov trusses contain all the necessary and sufficient information for solving the position analysis of all derived Assur kinematic chains [166].…”
