摘要
用于492Q发动机的JCQ净化消声器采用稀土小球为催化剂,用正交频带加权优化法优选消声器结构参数,取得良好的消声、净化性能。
JCQ depurant-muffler is adopted on 49ZQ engine using small rare-earth element balls as catalyst and took the method of quadrature frequency band optimization to opetmize the configuration parameters. Good function on reducing noise and depuration were obtained.
