The complex planar multilink mechanisms are in increasingly wide use at light industry process equipment. With respect to the lack of a universal method for these mechanisms’ kinematic studies evident is the relevance of multilink mechanisms’ kinematic analysis. This research was purposed onto developing an operational sequence for kinetic research of a complex planar mechanism’s base link points’ velocities using a graphic-analytical method departing from the theoretical mechanics’ provisions about instantaneous velocity center of the mechanism links, moving by plane-parallel model. The base-link points’ velocity vectors of the Assur group third class third order for complex planar mechanisms have been analyzed by graphic-analytical method, determining the position of instantaneous rotation centers of mechanism connecting rods. This reduces the amount of graphical constructs consequently increasing their accuracy.
