Development of the hydraulic system of the Stewart platform
The Stewart platform allows simulation in six degrees of freedom. It consists of two irregular hexagons connected by six actuators – hydraulic cylinders. The controlled simultaneous retraction or extraction of the piston rods from the tubes of the hydraulic cylinders changes the length of each leg, achieving the movement of the upper moving platform, which is described using a mathematical background.
Compatibility of filtering materials with ionic hydraulic fluids
Efficient filtering is often crucial in the field of machines and devices, as the safe, reliable, and long-term as well economical operation of the entire system depends on the efficiency of the filter. This is especially true for heavily loaded hydraulic devices. In these devices, the efficiency of the filter and the ability to filter depend on various factors.
Development of miniature proportional hydraulic valve to control the movements of a humanoid robot
To control a hydraulic humanoid robot, it is necessary to design and optimize a hydraulic proportional valve with the lowest possible mass and size. The valve for the robot’s rapid movements must not only be compact, but also allow high flow rates while minimizing internal leakage.
