Abstract: A controllable fluid damper (22) is employed in a seat suspension system. A microprocessor (42) receives successive signals from a displacement sensor (44) and computes a rate of displacement. This displacement rate is used to determine an appropriate control signal for the damper (22) to provide the desired isolation of the seat occupant from the vibration input to the frame. A rate control method is disclosed as a preferred control technique for providing the desired isolation.

Abstract: A radially soft drive coupling for reducing vibration transmitted across the coupling in certain marine drive applications. Elastomeric elements (54, 56) are bonded to the hub (22) and in frictional engagement with the housing (42). The elastomeric elements (54, 56), interconnecting the hub (22) and housing (42) are precompressed by an amount which is at least in the range of 15-20 % to produce significant radial and torsional softening of the spring rate of the elastomer. The radial spring rate whose magnitude expressed in lb/in is in the range of between one half and three times the magnitude of said design torque level expressed in 1b-in. Frictional engagement of the elastomeric elements (54, 56) with the housing (42) slips when a design torque is exceeded.

Abstract: Actuators (19L, 19H) for active vibrational energy control systems are frequency focused. The high-frequency cancellation function is decoupled (18L, 18H) from the low-frequency cancellation function to enable the size, force, number and placement of the actuators to be optimized. A hybrid system (not represented) employing structural actuators to cancel low-frequency vibrations and speakers to cancel higher-frequency vibrations is also taught.

Abstract: An active control method and apparatus for controlling vibration or sound wherein the computational burden to adaptively update the control filter within the update model is reduced. The apparatus includes means (not represented) for producing an input signal (36) for input to the update model (22) and the reduction block (26), means (not represented) for generating an error signal (41), and an output device (25) for canceling sound and/or vibration at a selected location. The method uses a gradient descent algorithm such as the filtered-x LMS algorithm and replaces the long filter model (23, 24) with a shortened length filter model (28, 30, 30'). Error signal information together with the output information from the shortened length filter model are used to update the coefficients of the control filter (32) according to an update calculation method. The shortened filter model only contains frequency response information at the L frequencies of interest. Because of the reduced amount of information contained in the shortened filter model, more updates per unit of time can be performed on the control filter(s) or a smaller or fewer processors or CPU's may be utilized. The method has applicability to feed-forward and feed-back type systems and also to systems using a waveform generator for supplying the input signal. The reduction method may be implemented on-line or off-line.
