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。 相似文献

This article presents a multidisciplinary approach of railway pneumatic suspension modelling: both multibody and pneumatic aspects are taken into account. The work aims at obtaining a realistic model of the secondary suspension and coupling it with a multibody model of a train. Various components of the pneumatic circuit such as bellows, tanks, pipes and valves are taken into account. The article focuses on the bellow–pipe–tank subsystem for which several modelling approaches are presented and compared. Differences between differential and algebraic models are highlighted, and an application-dependent choice between them is suggested. A complete model of the pneumatic circuit is then obtained and coupled with a multibody model of the train. As a result, the behaviour of a suburban train equipped with a pneumatic secondary suspension is analysed, in particular undesired oscillating motions which affect the comfort. Topological modifications and improvements of the suspension are also investigated and discussed. 相似文献

The article presents a survey of diverse methods for validation of pneumatic train brake modelling. Various experimental measurements of railway pneumatic brakes were made chiefly on a test stand at Poznań University of Technology; other test stands and some results have been taken from the literature. The measurements, some of them unconventional, were performed on separate pneumatic elements, brake devices, the brake pipe and fragments thereof. Mechanical devices were also included. The experimental measurement results were used for the verification of numerical models and for the determination of parameters. The latter was partially performed using an optimisation method. 相似文献
