Parallel stiffness
WebApr 10, 2024 · The cable-driven parallel robot (CDPR) is a special class of a parallel robot, in which the end effector (EE) is supported in parallel by m cables, which are driven by n actuators. The position and orientation of the EE of the CDPR is controlled by flexible cables, and not by rigid links, in contrast to conventional parallel robots. WebDec 30, 2015 · However, I believe this cannot be proven without FEA software or the direct stiffness method, which would be too lengthy and complex to present here. This can be solved once you know your structural analysis. You'll need to solve the entire structure for its internal forces and then you can calculate each of the rods for their deflections.

WebThe total stiffness of groups of elements are added up in series or in parallel (just like resistors in an electrical circuit): The sum of a collection of elements in series (e.g. Fig 1; k₄ & k₅) are added as follows: k = 1 / (1/k₁ + 1/k₂ + 1/k₃) The sum of a collection of elements in parallel (e.g. Fig 1; k₆ & k₇) are added as follows: WebMay 15, 2024 · Stiffness is one of the most important properties of a mechanism. Broadly speaking, the stiffness matrix maps the applied loads with the displacements of the rigid bodies in static conditions. As a result, stiffness clearly affects the accuracy and repeatability of the location of the end-effector.
