A sequence of actions is developed and a kinematic analysis of a complex planar mechanism of the fourth class with a structural group of links of the second order is carried out using mathematical models implemented in MathCad. The kinematic analysis is performed by the graphoanalytical method for validation purposes. The provisions of the theory of mechanisms and machines on the structural design of mechanisms are taken into account. The Assur singular point of a structural group of links of a complex mechanism is used. It is confirmed that the kinematic analysis is performed correctly with an accuracy of at least 95%, which is typical for engineering analyses. The proposed sequence of kinematic analysis of a complex planar mechanism can be used for similar studies of mechanisms of the fourth and higher classes.
