Frequency Domain Abstracted Energy Modeling Method for System Design Regarding Noise and Vibration

Abstract

Manufacturers have been trying to reduce reworks in product development. However, the reworks are increasing recently, because of the complexity growth in order to satisfy higher demands. Noise and Vibration (NV) are typical problems causing the reworks, because an effective system design method for NV does not exist, although NV phenomena are generated from widely distributed causes in the system. This paper introduces an effective frequency domain modeling method for NV in system design. An example for an automotive vehicle demonstrates the characteristics and the effectiveness of the method.
