The use of complex plane mechanisms in processing equipment of consumer industry is increasing. The absence of a general method of kinematic
research of the fourth and higher class mechanisms allows us to accentuate the relevance of work on kinematic analysis of multilink
mechanisms. Purpose of the work is to develop sequence of actions for kinematic research of velocities of the link points of a fourth class
complex plane mechanism using the method based on the provisions of the “Theoretical Mechanics” course on instantaneous velocity center
of links of the mechanism, which have plane-parallel motion. The velocity vectors of link points of the second order fourth class structure
group of complex plane mechanism are analyzed using grapho-analytical method, which provisionally modified initial mechanism has led to
a class reduction of mechanism and allowed to conduct its research.
