Abstract:
Engine noise is considered significant aspect of product quality for light and medium duty diesel engine market applications. Gear whine is one of those noise issues which is considered objectionable and impacts the customer perception. Gear whine could results due to defects in the gear manufacturing process and/or due to inaccurate design of the gear macro and micro-geometry. The focus of this technical paper is to discuss gear whine considerations from the production plant perspective. A gear whine case study is presented on the data collected on one of the Cummins diesel engines in the production environment. This paper also includes quick overview of measurement process, test cell environment, noise acceptance criteria considerations. This paper highlights the benefits of using production facility for developing next generation of product development from whine perspective. Gear whine data acquired on limited samples of prototype engines is analyzed and presented to illustrate the importance.
