Abstract
A device for affecting noise, vibration, and harshness (NVH), for instance, reducing the NVH. The device includes a pouch, which further includes a magneto-rheological material. The pouch has a resonance frequency of vibration. The device further includes one or more coils associated with the pouch. The device is configured to activate the one or more coils associated with the pouch, which causes a property of the magneto-rheological material of the pouch to change and thereby shifts the resonance frequency of the pouch.
Claims20
A device for affecting noise, vibration, and/or harshness, NVH, the device comprising:
- a pouch including a magneto-rheological material, wherein the pouch has a resonance frequency of vibration;
- and
- one or more coils associated with the pouch;
- wherein the device is configured to activate the one or more coils associated with the pouch, which causes a property of the magneto-rheological material of the pouch to change and thereby shifts the resonance frequency of the pouch.
A system comprising at least one vehicle component and a device (100, 302), wherein the device is arranged on the at least one vehicle component and that at least one vehicle component is susceptible to NVH and/or is arranged between two vehicle components susceptible to NVH;
- the device comprising a pouch including a magneto-rheological material, wherein the pouch has a resonance frequency of vibration;
- and
- one or more coils associated with the pouch;
- wherein the device is configured to activate the one or more coils associated with the pouch, which causes a property of the magneto-rheological material of the pouch to change and thereby shifts the resonance frequency of the pouch.
A method of operating a device for affecting noise, vibration, and/or harshness (NVH),
- wherein the device comprises a pouch including a magneto-rheological material, the pouch having a resonance frequency of vibration,
- and one or more coils associated with the pouch;
- and
- the method comprises:
- activating the one or more coils associated with the pouch, which causes a property of the magneto-rheological material of the pouch to change and thereby shifts the resonance frequency of the pouch.
