The Problem of Optimal Operation Speed of Positional Hydromechanical Drive Systems

The paper solves the problem of optimal operation of the positional hydrodrive dynamic system with hydraulic communication lines. The developed generalized structure of the hydrodrive dynamic system makes it possible to introduce the methods to solve the problems of optimal speed of operation and evaluation of output factors (based on transfer time, supplied power, positional accuracy, etc.).The use of the consequent simplication method of the multimass mathematical model results in finding a rational solution of the multicriteria problem of structural and parametric optimization with minimal timetable and capital inputs. The paper reviews the results of the experimental investigation which prove the adequacy of the proposed hydrodrive model and suboptimal trajectories of its output member displacement when managed by hydromechanic control units.
