摘要 为了解决民航飞机液压系统试验测试验证工作的诸多挑战,对虚拟试验技术在试验与评价工作的应用进行了研究,提出并研制了一种基于虚拟试验技术的民航飞机液压系统虚拟性能样机平台,描述了该平台的整体架构、功能模块和虚拟仿真试验的工作流程。该平台具备液压系统模型开发、集成仿真、参数优化等功能,利用泵出口压力脉动仿真测试分析等试验初步验证了该系统的计算可信度。研究结果表明:该性能样机平台能够有效开展液压系统设计优化和虚拟试验验证,平台灵活性强,虚拟试验方法合理;通过前期研究,为进一步扩大后续应用范围奠定了很好的基础。 In order to solve the many challenges of civil aircraft hydraulic system test verification work,the virtual test technology was investigated in the application of test and evaluation,a virtual property of civil aircraft hydraulic system prototype platform based on virtual test technology was developed,the overall architecture of the platform,function modules and the work flow of virtual simulation test were described. The platform has the function of hydraulic system model development,integrated simulation,parameter optimization. The calculation of system reliability was verified by the pump outlet pressure pulsation test analysis. The experimental results show that the performance of the prototype platform can effectively carry out optimization design of hydraulic system and the virtual test platform,the platform has strong flexibility,and virtual test method is reasonable; through previous research,which lay a good foundation for further expanding the application scope of the follow-up.
