Abstract
In order to study the performance simulation of the aircraft cargo door electrohydraulic system in the flight environment, the electrohydraulic co-simulation method is put forward to analysis the influence of the stochastic wind field on the aircraft cargo door electrohydraulic system. To work it out, the numerical simulation of the turbulent wind field and the discrete gust makes the high-altitude wind stochastic field have the random amplitude and time, then use the high-altitude wind stochastic field and the aircraft cargo door electrohydraulic simulation system to build the virtual prototype system. Use the virtual prototype system to get the relationships of data transfer among the electronic-controlled system, hydraulic system and the wind load. Since the aircraft must complete the open function in the different velocities, the cargo door must be put in the different flight velocities to get the functional examinations. At last, use the relationships of data transfer to finish the functional examinations, and get the opening time distribution under the different velocities.
