Experimental Analysis and CAE Optimization for Exhaust Noise of the Diesel

Abstract: Based on compute analysis engineering (CAE), the performances of acoustic and fluent for muffler comprehensively were analyzed and optimized in the paper. First, aiming at the heavy exhaust noise of diesel engine, bench experiments of measuring independently were designed and carried out, the frequency spectrum of exhaust noise was achieved, combining with simulation analysis of the finite element, acoustic and fluid performances of the original muffler and respective muffling cavities were analyzed, whose sho… Show more

“…Ranjbar investigated passive noise reduction methods in muffler and conduct an experimental examination [15]. Zhang et al optimized the exhaust system of the diesel through computer analysis engineering and made the loss of exhaust noise more than 10 dB [16]. Steblaj et al proposed an adaptive silencer and improved the transmission loss obviously [17].…”
