Introduction to Brake Noise, Vibration, and Harshness 1 Day | Classroom Seminar I.D.# C1337 Brake Noise, Vibration, and Harshness (NVH) is recognized as one of the major problems currently faced by the automotive manufac- turers and their suppliers, with customers warranty claims of more than $100 million per year for each manufacturer. With increasing consumer braking performance expectations, automotive OEM’s and suppliers need the ability to predict potential problems and identify solutions during the design phase before millions of dollars have been spent in design, prototyping, and manufacturing tooling. This seminar provides an introduction to brake NVH, including a concise summary of the various brake NVH problems, current lab and vehicle measurement techniques and SAE global standards which are utilized to characterize the noise correctly in order to get the best option/solutions quickly. The information provided will serve as an excellent foundation for understanding and characterizing brake NVH issues and is an excellent primer to the SAE seminar, Brake Noise Problem Resolution (ID# C0831), also taught by Eric Denys. • Describe the components of a brake NVH dynamometer • Configure and perform dyno and vehicle brake NVH tests measurements • Utilize SAE J2521, the only international standard for brake NVH dynamometer evaluation • Interpret basic noise and vibration data in the time and frequency domain • Explain the premise behind various SAE Standards related to brake NVH Who Should Attend The information in this course is relevant to a wide audience, from the brake test technician who seeks to understand more about Learning Objectives By attending this seminar, you will be able to: • Describe NVH and brake NVH • Identify the various brake NVH problems
