An automated, pre-programmed, multiplexed hydraulic valve actuator is described. The valve is membrane-based and normally open. In contrast to the membrane-based pneumatic valve, the hydraulic valve uses hydraulic liquid to exert the control pressure. The line pressure is controlled with a roller moving over a prefabricated topology. Multiple rollers, each traversing its own track, are assemble...
The thermal impedance Zth(jω) has been measured for a transistor fixed on a cooling fin. We have put the setup inside a cilindrical chimney with an inner diameter around cm and various heights H ranging from to cm. The enhancement of the natural convection cooling by the chimney is clearly demonstrated by means of Nyquist plots of the thermal impedance. Depending on the insertion distanc...
In order to optimize the design method and improve the performance of hydraulic retarder, the numerical simulation of multi-field coupling of heat, fluid and solid is carried out to hydraulic retarder, based on the numerical computation and algorithm of heat-fluid coupling and fluid-solid coupling. The computation models of heat-fluid coupling and fluid-solid coupling of hydraulic retarder are ...
