Embodiment Construction

[0015] Baffles can be used to reduce noise and vibration without adding significant weight to the frame. The performance of the diaphragm can be measured by the reduction of noise and vibration, usually by analyzing a specific frequency range. Certain uses may be susceptible to different noise and vibration frequency ranges depending on location, type of vehicle, usage, etc. Baffles can be set to reduce more specific frequency ranges for specific applications. Custom partitions can be achieved by incorporating metal inserts into the partition. The size, shape and / or weight of the metal inserts can be tailored to a particular application in order to alter the performance characteristics of the separator. Modifying the separator by adding and / or changing the size of the metal inserts can greatly enhance the performance of the separator, customizing the separator for a specific application without requiring costly and time consuming tooling changes. Additionally, the outer dim...

Abstract

A baffle (10) is provided that includes at least one carrier (12) and a sealer (18) disposed in a recess (16). When placed in a cavity, such as a vehicle cavity, sealer (18) also expands into the cavity to seal the cavity. Baffle (10) can be modified by including an insert (28) within carrier (12) to increase the weight, density, and structural rigidity of baffle (10), without altering the exterior dimensions of baffle (10). A baffle (10) that includes an insert (28) can be customized based on a particular application, without requiring time-consuming and expensive tooling changes.

Description

technical field [0001] The present invention relates to a separator. Background technique [0002] Various commodities benefit from having a rigid structural base while ideally keeping weight low. In many cases, these items are manufactured with a frame defining an internal cavity. For example, the frame may be formed from metal such as steel, and making a portion of the frame hollow (ie the cavity) will reduce the weight of the frame. However, cavities may contribute to increased sound and vibration. Common methods for mitigating additional sound and vibration within a cavity include sealing the cavity, for example by using baffles. Sealing cavities is an important aspect of designing items that are lightweight, while also providing valuable vibration damping and noise cancellation. This technology is commonly used in vehicles, including cars and airplanes, but can be used in other industries as well. Typically, a bulkhead is placed across the cavity and a sealing mate...
