Development of a hydraulic robot for tunnel drilling : manipulator kinematics and tracking control
Zhong, George Guozhen (1996-01-01)The purpose of the research described in this thesis was to contribute to the analytical and experimental development of a new hydraulic tunnel drilling robot which could be used to replace the present tedious, but ... -
Fault simulator for proportional solenoid valves
Bhojkar, Amit Arvind (2004-07-22)Proportional Solenoid Valves (PSV) have been successfully used in the hydraulic industry for many years due to the benefits associated with higher accuracy compared to on/off solenoid valves, and the robustness and cost ... -
Investigation of spring valves
Campbell, Douglas William (1974)This thesis presents a study of spring valves with the ultimate aim of using them as high pressure hydraulic flow-control valves for agricultural applications. A closed helical coil spring, when pressurized, will provide ... -
Modeling and experimental evaluation of a load-sensing and pressure compensated hydraulic system
Wu, Duqiang (2003-12-01)Heavy load equipment, such as tractors, shovels, cranes, airplanes, etc, often employ fluid power (i.e. hydraulic) systems to control their loads by way of valve adjustment in a pump-valve control configuration. Most of ...
