Global NVH Matrix for Brake Noise - A Bosch Proposal 1999-01-3405

A new NVH matrix for brake noise test rigs is presented which combines the specifications of the European drag mode test developed by the AK Noise (‘Arbeitskreis Geräusch’) with US-American in-stop tests. Additionally parts, of the AK Master lining selection dynamometer program are included in the proposed procedure to correlate friction and noise. The NVH matrix has been assigned a SAE concept number J 2521.To aid data evaluation and correlation of dynamometer and vehicle results, a post-processing system has been developed offering high flexibility and fast data visualization.
