Description

A cylindrical joint is shown in the diagram below with the two bodies that it connects.  A cylindrical joint allows the two connected frames to translate along and rotate about a single common axis; this joint type prevents all of the other relative motions of the two frames. In the diagram below, the joint displacements, s and θ, represent the relative translation and rotation, respectively, of the end frame, x2y2z2,with respect to the start frame, x1y1z1. In this example, both x1 and x2 remain parallel to the joint axis during the motion of the two bodies.
