项目摘要

To accomplish the wave simulator, a fast opening gate valve was developed. The formation of the pressure wave in a simulator are reproduced with a good quality.The effects of porous wall and cavity space for super frequency noise are investigated numerically and experimentally. The numerical analysis was developed on the attenuation and distortion of a pressure wave propagating in a wave simulator with various porous wall and cavity.The waveform of the pressure wave in the tube calculated by the present method, taking both fluid friction on the wall and the effect of the ballasted track into account, is in good agreement with the experimental data, so that the present numerical method of calculation seems to be reasonable.Experimental data shows the possibility of the present alleviative method, and the effects of the partition plates and cavity space are clear. Optimum location of porous plate are found and the effect of patition plate in a tube have been clarifed.
为了实现波浪模拟器,研制了一种快速开启闸阀。用数值和实验的方法研究了多孔壁和腔体间距对超高频噪声的影响。对压力波在具有不同孔壁和孔洞的波浪模拟器中传播的衰减和变形进行了数值分析。用该方法计算的管内压力波波形,既考虑了壁面上的流体摩擦,又考虑了道碴轨道的影响,与实验结果吻合较好,表明本文的数值计算方法是合理的。实验数据表明,本文提出的缓解方法是可行的,隔板和空腔空间的影响是明显的。找出了多孔板的最佳位置,阐明了配料板在管内的作用。
