报告人简介:
Dr. David Herrin is an Associate Professor in Mechanical Engineering at the University of Kentucky.  He received both his B.S. and M.S. degrees from the University of Cincinnati and his Ph.D. from University of Kentucky.  His research specialization is acoustics and vibrations.  He directs the Vibro-Acoustics Consortium, a group of companies interested in the development and use of noise prediction technology, and is the author of over 100 journal and conference papers.
报告简介:
Silencer and muffler design is primarily accomplished via cut-and-try approaches in many industries. Noise issues are identified close to production and mufflers are designed and tested.  While acceptable performance is eventually achieved, designers often do not understand why their changes improve or degrade the muffler performance. Additionally, mufflers often include unnecessary features that increase the pressure drop while doing little to combat noise. In this presentation, the basics of muffler and silencer design are reviewed.  After which, a design process for mufflers is recommended. The steps that may be taken during the 1) clarification of task, 2) conceptual design, 3) detailed design, and 4) prototyping phases are outlined, and the process is demonstrated on a cross-flow type muffler.
