Abstract
Designing modern mechanisms and machines is a very complex and iterative process. One of its first stages is the kinematic analysis of mechanisms followed by structural, dynamic, kinetostatic, etc. The scheme of an asymmetric rhombic mechanism with a developed drive arm of the working group is investigated. The kinematics of the characteristic links points of this mechanism is considered: their kinematic pairs and centers of mass. The kinematics of points and links of this mechanism is considered. The main dependencies for determining the analogs of the velocities and accelerations of points and links of the mechanism are presented. To solve the kinematics tasks the Zinoviev’s method of vector contours was used. The results of the kinematic analysis can be used for dynamic and kinetostatic research of the asymmetric rhombic mechanism with a developed drive arm of the working group, as well as for optimization synthesis of its design.
