摘要

摘要: 大型飞机结构强度试验中，通过流量估计和载荷估算选取阀控液压缸系统，可能导致阀控缸系统匹配性较差，造成其工作能力不足，影响结构试验加载系统的加载性能。为此，基于AMESim软件，建立阀控液压缸系统的模型，对其匹配性进行仿真分析，给出了阀控缸系统比例增益的边界值，并对该方法进行物理试验验证。结果表明：本文方法有效，使得结构试验加载设备工作性能有较大提升，为大型飞机结构试验的阀控缸系统的选型和设计，同时为后续阀控缸系统匹配性数据库的建立提供了理论参考。

Abstract: In aircraft structural strength testing, the servo valve is chosen by the nominal rate of flow, and the hydraulic actuators is chosen by its load capacity and stroke, which will affect the matching characteristic of valve controlled hydraulic cylinder. Based on AMESim software, the valve controlled actuators model is built and the matching of valve controlled actuators is simulated and analyzed to obtain the boundary values of proportion gain. A physical test is conducted to verify the proposed method. The results show that the present method is effective. The study provides a method to choose and design servo valve and hydraulic actuators, and gives a theoretical basis for programming database for matching of valve controlled hydraulic cylinder.
