    摘要:

    为优化设计2D伺服阀并提高其测试的准确性和高效性,结合虚拟仪器和高速数据采集技术,开发一套2D伺服阀的测控系统,包括参数设置、数据采集、数据存储及分析等功能。通过对10通径2D伺服阀进行测试,结果表明:该测控系统能够实现不同工况下2D伺服阀的静动态特性及频响测试;静态特性显示阀芯轴向位移与流量成线性关系,且滞回非常小;当系统压力为14 MPa、阶跃响应时,伺服阀轴向位移的上升和下降时间分别为9和7 ms;当敏感腔体积加倍,系统压力为13 MPa时,2D伺服阀会发生自激振动和啸叫,且振动基频约为1 300 Hz。

    Abstract:

    In order to optimize the design of two dimensional servo valve and improve test accuracy and efficiency, a measurement and control system for two dimensional servo valve was developed with virtual instrument and high speed data acquisition, which had parameters setting, data acquisition, data storage and analysis functions. Through the test of two dimensional servo valve with size 10, the results show that test system can realize the static and dynamic characteristics and frequency response tests under different working conditions; the static characteristic shows that the axial displacement of the valve spool is linear with the flow rate, and the hysteresis is very small; when the system pressure goes up to 14 MPa, the rising and the descent times are 9 and 7 ms respectively under step response; when volume of sensitive cavity is doubled and the system pressure is set to 13 MPa, the selfexcited oscillation and screaming of the valve occur, and the fundamental frequency of the signal is about 1 300 Hz.
