Abstract :
For one exhaust muffler, this paper researches its performance of flow and noise. Muffler´ comprehensive evaluation system and DoE development flow are built. RBF mathematical models of evaluated objectives are established to look for Pareto optimal solutions. According to design request, this paper chooses and evaluates optimized projects from Pareto solutions. The result shows that in low and middle speed anechoic effect of optimized Project-6 enhances more, volume efficiency and power decrease less, and the comprehensive performance is best.
