The Design and Analysis of a Muffler Based on Virtual.lab

摘要

In this paper, we analyzed the muffler acoustic performance by the finite element method and Virtual.lab. We changed the simple expansion chamber muffler size and expansion ratio related, expansion cavity length, and the number of expansion chambers effectively to improve the muffler. Through muffler design complexity and numerical simulation we analyzed the impact of external factors such as temperature, flow rate, etc. for muffler performance.
