Abstract
A method of and apparatus for damping vibration such as sound in a vibration generating device such as an appliance. A constraining layer and an adhering layer are provided. The adhering layer including a viscosity enhancing material such as a cellulose fiber, and an adhesive material. The constraining layer is adhered to a surface of an device with the adhering layer.
Claims27
A method of damping vibration in a vibration producing device, comprising the steps of:
- providing a constraining layer;
- providing an adhering layer, said adhering layer including a fibrous carrier material and a viscous adhesive material applied to said fibrous carrier material, said fibrous carrier material enhancing said viscosity of said adhesive material;
- and
- adhering said constraining layer to a surface of said vibration producing device with said adhering layer.
An appliance comprising:
- means for performing work;
- at least one surface producing sound in response to vibration;
- and
- a vibration damping system, including a constraining layer, and an adhering layer, said adhering layer including a fibrous carrier material and a viscous adhesive material applied to said carrier material, wherein said carrier material enhances said viscosity of said adhesive layer and wherein said constraining layer is adhered to said at least one surface by said adhering layer.
A method for reducing creep in a sound damper system including a constraining layer and an adhering layer adhering said constraining layer to a surface of a vibration producing device, comprising the step of:
- forming said adhering layer by applying a viscous adhesive material to a fibrous carrier material such that the viscosity of said viscous adhesive material is enhanced.
A vibration damping system comprising:
- a constraining layer;
- an adhering layer, said adhering layer including a fibrous carrier material and a viscous adhesive material applied thereto, said fibrous carrier material enhancing the viscosity of said adhesive material.
A vibration damping system comprising:
- a constraining layer;
- and
- an adhering layer having an adhesive material and a core of one of foam and plastic, wherein said adhesive material coats said core.
