ON THE CONTOUR METHOD OF KINEMATIC ANALYSIS OF THE 2nd CLASS MECHANISMS

摘要

There is presented a method for the determination of the transmission functions of order 1 ad 2, of the velocities and accelerations respectively, in a simple kinematic chain. The procedure, based on the transformation of the outline equations for rotating the coordinates axes, replaces the solving of the linear equations system with the solving of a single equation. The method allows to find the unknown functions with their compact form, being applicable to the kinematic analysis assisted on the computer of the II class groups/mechanisms. It is illustrated by example the application of the procedure in the case of the RRT type dyad.
