DRIVING NVH REFINEMENT OF NEXT POWERTRAINS GENERATION THROUGH VIRTUAL DESIGN
Videoconference Room – DIME Department of Mechanical Engineering for Energetics – Via Claudio, 21 Naples
Chairman : Mario J. Felice
Manager, Powertrain NVH CAE Department -
Ford Motor Company, USA
NVH ( Noise, Vibration, and Harshness) is one of the most important attributes in automotive design because it directly affects the customer’s perception of vehicle comfort, refinement and overall quality. A critical source influencing the vehicle NVH performance is the powertrain. Powertrain NVH can be categorized into two aspects, “wanted” and “unwanted”.The wanted aspect has to do with designing the powertrain to provide a pleasant and delightful sound that is smooth and powerful. This is known as Sound Quality. The unwanted aspect are associated with unintended error states resulting in annoying and irritating noises. This seminar will cover in details these NVH phenomena as they relate only to powertrain excitation. Lecture topics include:
