摘要
液压能源系统振动引起的管路失效问题突出,严重威胁飞机液压系统的可靠性。为了深入研究液压系统振动特性的优化控制,考虑了频率相关摩擦模型的传递矩阵法计算流体管路的频率特性,同时采用面向对象的编程思想,在Visual Studio 2010/MFC软件开发平台上,自编基于流程图的飞机液压能源系统振动特性仿真软件(HCAD-1.0),为液压系统振动特性分析提供了方便、快捷的途径。对国内某型飞机液压能源系统振动特性进行仿真对比分析,结果验证了缓冲瓶和支管对压力脉动的优化控制作用,为液压能源系统振动特性优化控制提供了科学依据。
The pipeline failure problems caused by vibration of hydraulic energy system are becoming more serious,it is a serious threat to the reliability of aircraft hydraulic system.In order to study the simulation optimization of vibration characteristics of hydraulic system,the frequency characteristics of fluid pipeline are calculated using transfer matrix method considering the frequency-dependent friction based on the design of the hydraulic energy system of one domestic aircraft.Meanwhile,a configuration graphics simulation software（HCAD-1.0） basing on the flow chart has been developed with the object-oriented program concept on Visual Studio 2010/MFC Integrated Developing Platform（IDP）.A convenient and quick way for the analysis of vibration characteristics of hydraulic system is provided.The simulation comparative analysis of the vibration characteristics of the hydraulic energy system of one domestic aircraft is carried out with the software.The optimization effect of buffer bottle and branch pipe on the pressure fluctuation is proved.
