为测试铝合金液压阀岛溢流阀的静、动双态特性是否满足使用要求，根据铝合金液压阀岛系统结构及工作原理，在分析其试验要求的基础上建立了相应的静、动双态特性试验测试平台。通过对阀岛溢流阀的静、动双态特性的主要性能指标进行测试，得出相关结论。静态特性测试结果表明：被测溢流阀的调压范围符合技术要求，压力振摆较小，且压力偏移值在允许范围内；在额定压力下，流量较低时，被测溢流阀可得到更好的启闭特性。动态测试结果表明：被测溢流阀的压力超调率与试验流量和溢流阀的进口压力有关；试验流量和溢流阀的进口压力增大，被测溢流阀的压力超调量会增加；当改变被测溢流阀的试验流量和溢流阀的进口压力时，被测溢流阀的压力上升时间及压力调整时间均随之变化。

In order to test whether the static and dynamic double-state characteristics performances of the hydraulic valve terminal of aluminum-alloy can meet its demands or not .According to its structural and working principle ,the static and dynamic double-state characteristics test system platform was established based on analyzing its experimental demands .And drew the relevant test results after the relief valve double-state characteristics were test .The static characteristics results indicated that the relief valve meets the technical requirements ,the regulating vibration pressure is small ,and the offset value is in the permitted range .Under the rated pressure condition ,if the flow rate is low ,the relief valve can get better on-off characteristic .The dynamic characteristics test results showed that the pressure overshoot only has relationship with the test flow ,and has not with the setting pressure .The pressure overshoot will increase and the pressure debug time will decrease with the test flow increases ,but the respond speed will be improved.The pressure rise time and the pressure adjust time of the relief valve will be both changed with the test flow .
