| 摘 要： | 应用流体分析软件Fluent和发动机模拟软件GT-Power分别对某型号空滤器进气系统的气动性能和消声性能进行了模拟计算。分别研究了进出气管的管径大小和插入长度对空滤器进气系统的气动性能和消声性能的影响。研究结果表明,减小空滤器的进出气管直径均能改善空气滤清器进气系统的消声性能,但其气动性能有所恶化,而且通过比较发现,进气管的管径大小比出气管对空滤器的气动性能和消声性能影响更大;进出气管的插入对于此种结构的空滤器进气系统的气动和消声性能并无改善。文章最后根据空滤器消声性能的不足和发动机进气口的阶次噪声曲线,设计了一个谐振腔,改善了其噪声性能。

| Abstract: | The aerodynamic and acoustic performance of a type of air filter intake system was simulated using CFD software Fluent and engine simulation software GT-power. The influence of the diameter and insertion length of inlet and outlet pipe on aerodynamic and acoustic performance of air filter intake system was researched. Results showed that reduce the diameter of inlet and outlet pipe would improve the aerodynamic performance but deteriorate the acoustic performance. The insertion of pipe would not improve the aerodynamic and acoustic performance of this structure. In the end this paper designed a resonant cavity to improve the acoustic performance based on the order noise curve. |
