Numerical simulation of exhaust muffler An homogenized finite element method
RÉSUMÉ. L’objectif de ce travail est de calculer l’atténuation acoustique dans un pot d’échappement contenant des tubes perforés. On se place en régime harmonique et en absence d’écoulement, ceci nous amène à résoudre l’équation de Helmholtz. L’utilisation de techniques d’homogénéisation, nous permettent de prendre en compte la présence des tubes perforés à l’aide de condition d’impédance équiv...
متن کاملModeling and simulation of the acoustic behavior of a muffler in a passenger car exhaust system
Muffler is one of the main components of an automotive exhaust system, which reduces the noise of the exhaust system. In this paper, modeling and simulation of the acoustic behavior of a muffler is presented with the aid of an engineering software. For this purpose, firstly, an analytical model is presented to evaluate the sound transmission loss in cylindrical shells based on Sander's theory....
متن کاملFinite Element Simulation of Welding Distortion in Large Structure
Fusion welding is widely used in heavy industries to join different parts together. But sometimes welding-induced distortions cause problems like misalignment during assembling and make costs to remove them. Thus it is imperative to predict and mitigate them to improve weldments quality and also reduce in fabrication costs. This study at first will introduce inherent deformation method for pred...
متن کاملAnalysis of Roll Wear in Reshaping Using Finite Element Simulation
Reshaping process is a widely used method for producing tubes with non-circular cross sections. Owing to the friction between pipe and rolls, initial round pipe moves forward and consequently, it gradually formed into square or rectangular one. In practice, geometric profile of the rolls will be changed after a while. These changes would be detrimental the production of faultless products. Ther...
