Abstract: An analysis is first performed to determine the exposed frontal area and effective volume as a function of rotor angle for circular lobed helical screw turbines. It is shown that once the ...

Abstract: Bond graphs are used for finite mode representations of distributed system dynamics. As long as all inputs to the system are “efforts” in a causal sense, then no formulation problems exist. ...

Abstract: Bond graphs are used to construct finite mode, long wavelength models of multidimensional structures. These structures are, in some cases, either too large or constructed from so many physical ...

Abstract: A nonlinear, controllable vibration isolation device—the Variable Fulcrum Isolator (VFI)—is introduced. Methods of designing feedback control laws are presented. Computer simulations compare the rms ...

Abstract: High performance hydraulic motion control systems typically consist of a two-stage spool valve which controls flow into an actuator. Feedback of load motion allows an electrical signal into the ...

Abstract: Bond graphs are used to model the acoustic behavior of the respiratory system. The model includes the distributed dynamics of the upper airways while the lower passage generations are represented ...

Abstract: The potential for energy regeneration in vibration control systems is investigated. Such control systems hold the possibility of self-sustainability by alternately extracting and releasing energy ...

Abstract: The dynamic characteristics of fluid transmission lines with a parallel branching line are analyzed in both time and frequency domains using modal approximation techniques which enable us to use ...

Abstract: The utility of many controlled dynamic systems is impaired by excessive power consumption and related hardware. In this paper, the potential for energy regeneration in a broad class of dynamic ...

Abstract: Phase velocities and attenuation factors for the propagation of small amplitude long wavelength sinusoidal disturbances, measured in a tube with turbulent liquid flow, are reported. Three frequency ...
