中文摘要:
      液压阀作为液压系统的重要组成部分,其内部流体高速流动时会在节流阀口处产生空化现象,并由此产生噪声及振动。提出一种高速流场可视化测试方法,可以同步进行图像与数据采集,能方便、直观地对液压阀内部流场现象进行观测,同时获取噪声、振动等信息。对该测试方法获取的信息进行研究有助于为设计低噪声、低振动型液压阀提供理论依据。
英文摘要:
      Hydraulic valve is an essential part of hydraulic system. The flow field with high speed will produce cavitation which results in noise and vibration in throttle orifice. A method of visualization test was presented by which images and data could be collected synchronously for high speed flow field. By this way, not only the flow field in the hydraulic valve could be observed conveniently and intuitively, but also the noise, vibration and other information could be obtained. Research on the information collected by the method provides theoretical basis for designing hydraulic valve with low noise and low vibration.
