Brake Rotor Modal Frequencies: Measurement and Control 2010-01-1688

As part of the development of a new SAE Recommended Practice for brake rotor modal frequencies measurement and control, the SAE Brake NVH Standards Committee developed detailed recommendations for such measurement, data reporting and use in quality control. This paper addresses the need for formalizing measurement techniques of rotor modal frequencies and documenting the proper set up and measurement parameters. Additionally, a rotor mode classification system is proposed so that important rotor modes may be tracked. Statistical control of modal frequencies is presented and practical limits are defined
