HYDRAULIC JUSTIFICATION FOR THE OPERATION OF THE DEVICE FOR ALLUVIATION OFNARROW-PROFILEDAMS
Prirodoobustrojstvo, 2021The construction of protective dams is the most effective means of combating flooding. There are various ways to build protective dams. The alluvial method of constructing protective dams can significantly reduce the cost of their construction. The article describes a method and device for alluvial narrow-profile dams that allows the use of bottom ...

Variable Stiffness Mckibben Muscles With Hydraulic and Pneumatic Operating Modes [PDF]
Advanced Robotics, 2016 McKibben muscles have been shown to have improved stiffness characteristics when operating hydraulically. However, when operating pneumatically they are compliant and so have potential for safer physical Human Robot Interaction (pHRI).

Control Concept for a Hydraulic Mobile Machine Using a Haptic Operating Device
2009 Second International Conferences on Advances in Computer-Human Interactions, 2009A control methodology for the operation of a hydraulic excavator using a haptic operating device is developed. The main idea is to use position controllers for both the excavator and the operating device where both control loops output the reference position to the other, i.e., two position controlled systems are placed in a feedback loop with each ...

Operation of hydraulic prop and safety devices in dynamic loading regime
Journal of Mining Science, 1999The results of stand tests of mass-produced hydraulic prop of ground support in dynamic loading regimes are presented. Pressure propagation in the fluid filling the piston cavity is shown to be of wave type; the reasons of failure of the cylinder walls are elucidated. A device for protecting the hydraulic prop from dynamic loads is proposed.

A superimposed oscillation in the main force flow of a forming process is investigated. Therefore a tool system was developed. The oscillation in this system is generated by pulsating oil streams. As part of this research, the oscillation device is equipped with additional storage tanks, to generate a higher oil volume flow.
