The TL (transmission loss) is an important index to evaluate muffler performance. The
design of muffler should not only consider acoustic performance, but also its volume …

Material removal mechanism depends on the material property and machining parameters
during machining process. This paper investigates the brittle removal mechanism of ductile …

The acoustical behavior of an elliptical chamber muffler having an end-inlet and side-outlet
port is analyzed semi-analytically. A uniform piston source is assumed to model the 3-D …

For multi-chamber silencers with non-uniform cross-sections at axial direction, the coupling
method based on subdomain division technique is proposed. The silencer is divided into …

Short elliptical chamber mufflers are used often in the modern day automotive exhaust
systems. The acoustic analysis of such short chamber mufflers is facilitated by considering a …

The sound attenuation of perforated dissipative circular mufflers including a folded resonator
and a short expansion chamber is investigated in detail by means of a two-dimensional …

In this paper, a nonlinear modeling and control method for magnetic bearings is designed,
considering the core material nonlinear high flux behavior for the first time. A combination of …

In this work, a three-dimensional analytical model is presented for the propagation of sound
in circular dissipative reversing chamber mufflers with perforated frontal plates and bulk …

Transmission loss (TL) of an elliptical cylindrical chamber muffler having a single side/end
inlet and multiple side/end outlet is analyzed by means of the 3-D semi-analytical …

Finite element method (FEM) is employed to determine the transversal modes of perforated
tube silencers, and the corresponding computational code is written. In order to validate the …
