Abstract: A harmonic balance method for underconstrained dry friction systems containing rigid body modes (HBM-RBM) is proposed. This method aims to overcome the encountered obstacle when applying the harmonic balance method to ...

Abstract: This paper presented the effects of finite dimensions of the sample and nonzero heat capacity of the strip on thermal conductivity determination with the transient hot-strip method. Through the ...

Abstract: A pump is not ideally designed to operate as a turbine. To improve the efficiency of a pump as turbine (PAT), the redesign of the PAT, according to the flow of the turbine, is required. ...

Abstract: The rotor-stator interaction of a rotating impeller and a stationary volute could cause strong pressure pulsations and generate flow induced noise and vibration in a pump used as a turbine ...

Abstract: One of the limitations of using the pump-as-turbine (PAT) technique is its relatively narrow high-efficiency operating range. When the system pressure head or flow rate decreases, trimming the impeller or replacing the ...

Abstract: In order to accurately obtain the dynamic characteristics of double involute gears (DIGs), according to the characteristics of tooth profile engagement, a tribo-dynamic model of DIGs with multiphysics coupling characteristics ...
