内容記述 | This paper deals with analysis for positioning of sound absorbing materials in a muffler having expansion chamber. Elements of absorber are modeled by 3D finite element, which having complex density and complex volume elasticity. By expanding the solution of complex eigenvalue problem with small parameter, equations of motion are derived using first order of asymptotic components. From the equations, contribution of damping elements on modal damping is derived in consideration of multiple modes. The sound absorber is arranged in muffler according to this contribution. It proposed a positioning method of sound absorbers within the limits of design feasible region and it applied to the expansion type muffler and availability of this method is verified. | |||||
