某型飞机投水作动装置解锁同步性影响因素分析

Analysis of Factors Affecting Unlocking Synchronization for A Certain Aircraft’s Water Drop Actuator

根据某型号飞机投水水箱三维数字样机及投水作动装置液压原理图,采用AMESim的液压库及3D Mechanical机械库搭建投水作动液压子系统模型,计算舱门开锁/上锁的时间和同步性。该模型的搭建考虑了影响投水性能的所有细节因素,为水箱作动系统结构的设计分析和优化提供了真实的仿真计算平台。在此基础上进一步分析了锁机构控制阀负载管路长度、主阀芯通径和阻尼孔大小对舱门开锁/上锁同步性的影响,其中管路长度和阻尼孔尺寸对同步性影响较大。上述分析结果为投水作动系统结构的进一步优化提供了理论依据。

According to the three-dimensional digital prototype of a certain type of aircraft water tank and the hydraulic schematic diagram of the water drop actuator, the hydraulic library of AMESim and the 3 D Mechanical mechanical library are used to build the model of the water drop actuator hydraulic subsystem, and the time and synchronization of unlocking/locking the cabin door are calculated.The construction of this model takes into account all the detailed factors that affect the performance of the water drop, and a real simulation calculation platform is provided for the design, analysis and optimization of the water tank actuation system structure.On this basis, the influence of the length of the load pipeline of the lock mechanism control valve, the diameter of the main spool and the size of the orifice on the synchronization of the door unlocking/locking is further analyzed.The length of the pipeline and the size of the orifice have a greater influence on the synchronization.The above analysis results provide a theoretical basis for the further optimization of the structure of the water drop actuation system.
