摘要
液压脉冲试验是飞机液压系统设计中的重要环节。为了深入分析水锤现象和主动控制产生规范的液压脉冲波形,对液压元件的可靠性进行考核,针对该测控任务的需求,提出利用虚拟仪器技术开发液压脉冲测控系统。该系统通过对测点的灵活安排可对关键位置的流体压力、流量和温度信号进行实时观测和记录,极大地方便了水锤波的理论研究工作。此外通过主动控制技术,可在高温、低温和室温等多种试验环境下对多种试验件进行试验。实践表明该系统具有性能完善、功能齐全和可扩展性强的特点。
Hydraulic impulse test is the important aspect in the design of airplane hydraulic system. In order to thoroughly analyze the phenomena of water hammer, actively to control the production of the normative hydraulic impulse wave, and test the dependability of hydraulic component, a measurement and control system of hydraulic impulse which aims at a requirement of measurement and control with the basis of virtual instrument technique is presented. By flexibly allocating the point of measurement, the system can in time observe and record these signal about fluid pressure, flow and temperature, thus it is greatly convenient to theory research in water hammer. In addition to using active control technique, the system can test various test component in varied environments such as high temperature, low temperature and normal temperature. It is showed that the system is full functional and easier to extend.
