Background. Stirring tanks are widely used for most of chemical, petrochemical, heat and mass transfer processes. Currently, the most common ones are stirrers with rotational impeller motion, but they often do not achieve the required level of heat and mass transfer. To eliminate this disadvantage, it is proposed to use a rotationally reciprocating stirred tank (RRST) with a planetary actuator. The purpose of the work is to construct and study a kinematic model of the mechanism.
Materials and methods. The aithors investigated the planetary mechanism’s kinematics using the Kutzbach-Smirnov method and processed the experimental data by methods of statistical analysis.
Results. The article describes the constructed kinematic model of the mechanism and the obtained equations for determining functions of the position, velocity and acceleration analogues of the planetary gear output link. The adequacy of the developed mathematical model was verified experimentally; the measurement errors were estimated.
Conclusions. The resulting kinematic model corresponds to the real object, so it can be used for further dynamic and force analysis of the machine, as well as for design of new highly effective rotationally reciprocating stirred tanks.

Key words

kinematics, planetary mechanism, rotationally reciprocating stirred tank (RRST), velocity plans, normal distribution, Pearson's chi-squared test, confidence interval
