    ENG: The purpose of the work is to develop an algorithm and a program for calculating the power parameters of the crank-slider mechanism, taking into account the proven in practice and well -recommended: analytical method of calculating the kinematics of the slider and the graph-analytical method of calculating the power parameters of the crank-slider mechanism. Research results. The new calculation method and an algorithm for determining the force parameters of the crank-slider mechanism. Scientific novelty. The new method for the analysis of force parameters of a crank –slider mechanism, which differs from the existing methods of graph-analytical and analytical methods by the use of a new calculation-analytical method of determining the linear and angular accelerations of each link of the mechanism for solving the kinetostatic equations of the mechanism as a whole. Practical value. The created algorithm makes it possible to perform a preliminary assessment of the force parameters of mechanisms and aggregates using crank-slider mechanisms at the stage of technological design, technical and economic calculation of new aggregates or modernization of existing equipment when changing technological regimes related with the production of modern competitive products, in particular, for the production of seamless pipes on mills with rollers for cold rolling of pipes.
