| Abstract: | Aiming at the problem of fatigue fracture at the welding between muffler cylinder and exhaust pipe, the CAE quantitative analysis method and modal analysis technique are used to analyze the cracked muffler. An improvement scheme of letting the exhaust pipe pass through the muffler cylinder is proposed. Meanwhile the theoretical and experimental modal analyses are done for the muffler before and after the improvement. Results of analysis show that the improvement measures are reasonable, and the reliability of the muffler is raised. |
