摘要： Magnetorheological-damper-based steering apparatus and methods for reducing steering wheel jerk resulting from off-road wheel impact are described. An example steering damper apparatus includes a magnetorheological (MR) rotary damper to be operatively coupled to a steering column shaft. The example steering damper apparatus further includes a sensor to detect an angular velocity associated with the steering column shaft. The example steering damper apparatus further includes a controller to energize the MR rotary damper in response to determining that the angular velocity exceeds an angular velocity threshold. The angular velocity threshold is associated with steering wheel jerk resulting from an off-road wheel impact.

摘要： A computer of an active vibration damping device calculates operation command values for an actuator from rotation information of a drive source, and corrects the operation command values in accordance with an internal temperature of the actuator. The computer applies a drive voltage to the actuator using a voltage duty ratio based on the corrected operation command values. The computer also estimates the internal temperature on the basis of an average duty ratio as an average of the voltage duty ratios in a predetermined interval.

摘要： A rotational signal of a generation source of a control object is detected and, when a rotational speed (frequency) varies, convergence values of filter coefficients of adaptive filters 33, 34 based on a previous control result corresponding to the frequency stored in a control device 11 are retrieved and set to the adaptive filters 33, 34 as initial values. The adaptive filters 33, 34 are updated by using the initial values of filter coefficients and output a control signal y(t) to an ACM (actuator) 3a. LMS arithmetic units 37, 39 read a reference signal calculated from the rotational signal and an acceleration signal (error signal) e(t) detected by a sensor 9 and carry out processing for updating the filter coefficients of the adaptive filters 33, 34. The adaptive filters 33, 34, based on updated filter coefficients, output the control signal y(t) to the ACM 3a.

摘要： Provided is a sound reduction or vibration damping apparatus that has a new sound control principle where the sound control principle is totally different from a known passive or active sound control apparatus. A sound reduction or vibration damping apparatus 1 includes a mass portion 11, spring portions 12a and 12b placed between the mass portion 11 and a structural member 13, and a control unit 4 for causing the spring constants of the spring portions 12a and 12b to continue changing. The sound reduction or vibration damping apparatus 1 is mounted on the structural member 13 to reduce sound passing through the structural member 13 or sound generated from the structural member, or damp the vibration of the structural member 13.

摘要： A system for managing noise and vibration in a vehicle includes a housing defining an internal cavity. A compliant member is attached to the housing and further defines the internal cavity. A magnet is operatively fixed to the housing in the cavity and has a magnetic field. A coil is positioned in the cavity and is configured so that there is relative movement between the coil and the magnet in the magnetic field in response to movement of the compliant member relative to the housing. A resistor is in electrical communication with the coil to form an electrical circuit. Relative movement of the coil in the magnetic field induces a current in the circuit that creates an opposing magnetic field, thereby reducing transmitted dynamic forces.
