ANALYSIS METHOD FOR DEDUCING NOISE OF MUFFLER USING FINITE ELEMENTS METHOD

摘要

An analysis method for attenuating the noise of a muffler using a finite element method is provided to save cost and time by using a simulation experiment through a computer. An analysis method for attenuating the noise of a muffler using a finite element method includes the steps of: modeling finite elements including upper and lower plates, an inner pipe and a baffle; detecting the natural frequency with respect to a modeled silencer; detecting the rate of vibration in surface of the modeled silencer; calculating the equivalent stiffness value of the silencer by integrating the rate of vibration in surface.
