Optimum Design Of Mufflers Hybridized With One-Connected Curved Tube Using The Boundary Element Method, Neural Networks, And The Genetic Algorithm, Ying-Chun Chang, Min-Chie Chiu, Ching-Chung Hsieh

Journal of Marine Science and Technology

Recently, research on new techniques for an economical muffler, which is hybridized with a single-connected curved tube, has been applied in the industrial field. Most researchers have explored noise reduction effects based on the transfer matrix method and the stiffness matrix method. However, the maximum noise reduction of a silencer within a constrained space, which frequently occurs in engineering problems, has been neglected. Therefore, the optimum design of mufflers becomes an essential issue. In this paper the shape optimization of a one-connected tube muffler with a fixed length is examined. In order to speed up the optimization assessment, a simplified …
