The experience of creating compact energy efficiency hydrostatic servo drive

Modern robotic systems require the use of servo drives. These drives due to the position sensor and the negative feedback ensure high accuracy motion parameters. In the case of autonomous systems to the drives and places even high power characteristics. Moreover, in most cases, it is impossible to pick up the motor so that the speed and torque on its shaft to meet required actuator. To reconcile these parameters using different types of gearboxes. The article justified and considered the selection criteria gear ratios for such transfers. However, in some cases it is necessary to carry out this evaluation during acceleration and braking. The article discusses the work of electro-hydraulic servo drive in the dynamic mode. Tracking is the angle of rotation of the output shaft. The mathematical model of the drive, which takes into account the power loss in each of the components of the transmission. In the numerical simulation studies the influence of the form of the front of the control signal and its effect on the value of the total energy consumption. The simulation results showed that there are optimal in terms of energy consumption waveform and time of action. In addition to the numerical experiment carried out as a physical one. The results of numerical and physical experiments have shown good convergence and thereby confirmed the validity of the findings.
