【 摘 要 】

The paper presents the calculation of the pressure of the hydraulic cylinder of the boom at the inlet to the throttle, which regulates the speed of lowering the boom with a load, which provides a non-cavitation operation mode of the hydraulic drive. The pressure calculation takes into account the change in the angular acceleration of the boom with a load and the deformation of the working fluid and the walls of the hydraulic cylinder.
