Article presents the results of mathematical modeling of the dynamics of a stirred tank with irregular motion of the impeller. The design of the apparatus with a stirrer is considered as a mechanical system with one degree of freedom, which is based on proposed by the authors planetary gear with elliptical wheels. The solution of the differential equation of motion of the stirred tank is proposed to be carried out by two methods: the energy-mass method and using the third-order Hermite interpolation function. There is presented a kinematic model of the mechanism, which describes the relationship between the geometric parameters of the links and allows you to bring the forces, masses and moments to the initial link. As an example, an analysis of the stirred tank according to the given initial data is carried out, there are calculated the moment of resistance on the impeller, the driving moment and the moment of inertia of the flywheel, which are of great importance at the design stage of the machine. The laws of motion of the input link are determined and constructed without taking into account and taking into account the installation of the flywheel. The convergence of the results obtained by various methods is confirmed.
