Abstract: 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.
