Introduction to Contemporary Muffler Design Techniques
This four hour seminar provides an introduction to the behavior of mufflers and silencers including a description of the two-port approach to muffler design. This seminar covers the acoustic simulation of muffler and silencer systems and the use of experimental methods to measure muffler performance. Following a review of basic muffler concepts and definitions, this seminar will focus on meeting design objectives such as insertion loss with a specified back pressure requirement. This seminar will show how modern software such as SIDLAB can be used to model both the acoustics and flow in achieving the design objective and the role that 1D engine simulations can play in providing important input. The final topic will cover optimizing muffler design to meet a specified design objective with a specified space constraint. The main focus is on IC-engine intake and exhaust systems, but most of the information is also applicable to any pipe or duct system.
