Abstract: A vibration reducing device that reduces the vibration of a control object includes a digital controller. A vibration state detection device detects the vibration of the control object and generates an analog signal of the vibration of the control object. An input-side bandpass filter has a passband that is narrower than a frequency range from a Nyquist frequency to a sampling frequency of the digital controller, and that contains no frequencies that are an integer multiple of the Nyquist frequency of the digital controller. The input-side bandpass filter allows a part of the analog signal that falls within the passband from the analog signal generated by the vibration state detection device to pass. An A/D conversion device converts the analog signal that has passed through the input-side bandpass filter into a digital signal.

Abstract: Moving fluids are subjected to acceleration forces in turns, contractions, expansions and when flowing around bluff bodies. These forces can result in losses that are much larger than friction losses. For internal flow contractions, it is known that constant acceleration will eliminate pressure losses by balancing the forces that cause these accelerations with changes in static pressure. This disclosure teaches how to provide constant deceleration forces in expansions (diffusers) by maintaining a constant area to shear surface ratio, known as hydraulic diameter. Also taught, is how to design a turn vane array that has a hydraulic diameter equal to the upstream ducting diameter. Lastly, that these design techniques apply equally well to external flow regimes and a simple calculation demonstrates this method. Constant Acceleration Fluid Dynamics, results in ducting and bluff bodies that have no losses other than friction.
