摘要
Abstract
An exhaust muffler of a digging machine is studied to find the weak frequency band with test and CAE method. With the internal structure characteristics of the muffler as design factors, the main sizes of anechoic components are parameterized based on DOE. The Latin square optimization experiment is done to analyze the noise elimination contribution of each muffler component. And the optimized muffler structural parameters are obtained through multi-objective optimization. Simulation result of the optimized muffler indicates that the noise attenuation performance in the target frequency band is significantly improved.关键词
