摘要： An oscillating apparatus comprises a cylinder, a piston reciprocatingly movably fitted in the cylinder, shaft members connected to the piston and extending out of the cylinder. The cylinder, piston and shaft members form an oscillator. An inlet and an outlet for an electro-rheological fluid are provided at each of two cylinder chambers defined in said cylinder by the piston. The apparatus further comprises voltage applying devices for applying electric voltage to the electro-rheological fluid passing through the inlets and outlets, respectively, so that applications of the voltage to the inlet of one cylinder chamber and the outlet of the other cylinder chamber are simultaneously effected and applications of the voltage to the inlets of both the cylinder chambers are alternately effected. With this arrangement, the switching-over of the closing and opening of the inlets and outlets are very rapidly performed by the application and removal of the electric voltage so that the piston undergoes vibration which is transmitted through the shaft members to an object, structure or the like, with the result that the object is controllingly vibrated and vibration to which the object is subjected is effectively damped.

摘要： Disclosed is a vibration control method being largely effective in vibration-proof even when a natural frequency is relatively low and its transmissibility of vibration is high and being thus effective in reducing vibration in a wide range of frequencies; and its apparatus. In the above method, vibration information of a vibration source as a reference signal and vibration information of a vibration-proof object as an error signal are inputted into an adaptive filter. The reference signal is processed by regenerating a filter coefficient on the basis of adaptive algorithm, to form a feedforward signal. In the other hand, vibration information of the vibration-proof object is inputted in a feedback calculating means, and a feedback control signal is formed on the basis of a feedback control rule. The feedforward control signal and the feedback control signal are synthesized, to form a drive signal for a vibration exciting means. The vibration exciting means is thus controlled and driven on the basis of the drive signal.

摘要： Acoustics or vibrations at a plurality of predetermined positions are respectively detected in the form of analog values, and the detected analog values are respectively converted into digital values. The digital values are subjected to digital filtering by using the digital values and filter factors, and at least one of the filter factors is changed such that the difference between the total sum of the results of digital filtering and a targeted value becomes minimum. The rate of contribution to an evaluation point is computed by using the results of digital filtering within a predetermined time when the difference becomes minimum, and the computed rate of contribution is displayed.
