Calculation of mathematical model of non-choking logging process with energy-saving hydraulic drive in MATCHCAD

During the movement of a tractor in conjunction with a non-choking grip on rough terrain in clearings, vibrations occur, causing surges of working fluid in the hydraulic system and high dynamic loads, which reduce the reliability of technological equipment and the assembly. One way to reduce dynamic loads and energy consumption is to use an energy-saving (recuperative) hydraulic accumulator. The article presents a calculation of a mathematical model taking into account external and internal forces acting on the harvested wood bundle and parameters of the energy-saving hydraulic drive, allowing to reduce the dynamic load and energy consumption of the working processes.
