The invention belongs to the technical field of aircraft landing gear fatigue test design, and particularly relates to an aircraft landing gear fatigue test control system which utilizes three emergency control two-position three-way valves to achieve accurate control over folding and unfolding of an aircraft landing gear. One-way throttle valves are arranged on the retracting and releasing actuator cylinder retracting control pipeline, the retracting and releasing actuator cylinder releasing control pipeline and the retracting and releasing actuator cylinder emergency control pipeline, rapid retracting and releasing control over the retracting and releasing actuator cylinder is achieved, in addition, an emergency control pressure reducing valve is designed and used for pressure reducing control, rapid switching of two kinds of pressure in one system is achieved, and the safety of the system is improved. According to the aircraft landing gear fatigue test control method, an extra landing gear emergency control branch does not need to be designed, the complexity of the structure and operation can be greatly reduced, the loading actuator cylinder is designed and utilized, corresponding load loading is carried out in the normal folding and unfolding process of the landing gear, and the aircraft landing gear fatigue test control method is convenient and efficient.

    本申请属于飞机起落架疲劳试验设计技术领域,具体涉及一种飞机起落架疲劳试验控制系统,其设计利用三个应急控制两位三通阀实现对起落架收起、放下的准确控制,且在收放作动筒收起控制管路、收放作动筒放下控制管路、收放作动筒应急控制管路上设置单向节流阀,实现对收放作动筒快速的收放控制,此外,设计利用应急控制减压阀进行减压控制,实现在一个系统中两种压力的快速切换,不需要设计额外的起落架应急控制支路,可极大降低结构、操纵的复杂程度,并设计利用加载作动筒,在起落架正常收起、放下过程中进行相应的载荷加载,方便、高效,此外,本申请还涉及一种飞机起落架疲劳试验控制方法。
