| With the rapid development of aeronautic sc-tech, the aviatic speed, height, coverage as well as the performance in battles has been improved a lot, and with more and more electronic facility equipped, there appears a growing demand of E-power on the plane, resulting to more and more complex structure and control of aero electronic source system. Therefore a stricter demand is laid on the capabilities such as dependability of air-planes. As one of the great-power loads on air-planes, the change of various index of aerial hydraulic has obvious effects on the whole power net. For a convenient and direct understanding of the effects of the hydraulic system, this article sets up the scheme for the model design and the emulating software on the basis of detailed analysis of the working characteristics of the hydraulic system beginning with the analysis of the relationship between the power source and the power-consuming loads through reasonable simplification of the power system. And the following chapters demonstrate the procedure of the establishment of the mathematic model of the aerial hydraulic system in the method recognizable for the system and the emulating model based on the flat of MATLAB/SIMULINK software with focus on the experiment design and disposal of parameter of the recognition system, also supplying with the results and its analysis. In the end, the process of the design and development of the model analysis software of the aerial power system is described and the division of the constituting software modules as well as the design plan of the connection under VB development circumstances and MATLAB emulating circumstances is illuminated in detail as well.As illustrated by the experiment results, the active and static performance can be reflected through emulating the operating characteristics of aerial hydraulic system under different conditions through the emulating analysis system of aerial power sources and the design of the model is accurate. And at the same time, the emulating software shows more steadiness and dependability in operation. Compared with the method which tests the performance of aerial power sources merely dependent on existent objects, the utility of emulating moles provides a new testing method of the aerial power source and saves a lot of human power as well as material. |
