Abstract

The present invention discloses a computer-implemented systerm for identifying potential squeak concerns between a pair of vehicle components. The computer implemented system comprises at least one computer, which is used for receiving CAD data, identifying a plurality of vehicle component pairs within a predetermined tolerance of each other, assigning a material description and material compatibility value to each of the pairs in each of the number of vehicle component pairs, and outputting the material compatibility values for each of the vehicle component pairs for use in identifying squeak concerns. Therefore, the system disclosed by the invention can at a minimum provide for less or no noise in the final product and, accordingly, reduce the customer dissatisfaction associated with vehicle use due to these persistent noises generated by their vehicle.

Description

technical field [0001] One or more embodiments of the invention relate to computer-implemented methods and systems for detecting possible noise conditions between components, and in some embodiments relate to analytical detection of squeak in vehicle component pairs. Background technique [0002] In modern technology, original equipment manufacturers (Original Equipment Manufacturers, OEMs) and their vehicle suppliers used to draw vehicle design hand-drawn diagrams have been replaced by computer-aided engineering (CAE) tools. OEMs and suppliers can use these tools to determine the best design parameters for their products. For example, CAE tools can be used to pinpoint problem areas in a vehicle design (such as impact noise and squeak), isolate the problem area, and fix the problem to prevent any possible noise in the final product. The prior art includes several examples of such automated methods and systems for detecting noise in vehicles. Some examples include U.S. Pate...
