Abstract
A methodology designed for practical computer coding is developed to implement the velocity analysis of mechanisms with a plane joint, that is, a joint consisting of two flat surfaces held in contact to permit one rotational and two translational degrees of freedom. The analysis utilizes the 3 × 3 dual-number coordinate transformation modelling of joints and links of a mechanism to develop the results in a compact form amenable to object-oriented programming of displacement and velocity calculations. The velocity analysis of the Tracta coupling, an RRERR mechanism (rotation-rotation-plane-rotation-rotation joints) that has been used as a constant-velocity shaft coupling, is given as an example for a mechanism with a plane joint. An explanation is given of the relationship between the calculated speeds and the physical speeds in a plane joint.
