Aiming at the problem that the physics experiment can result in long cycle and high expense in course of universal test platform design,a proposal was put forward to carry out computer simulation. The composing of aircraft fuel accessory universal test platform was introduceded.The simulation model of aircraft fuel accessory universal test platform was established by using AMESim,which was carried out to simulate the universal test platform system.The simulation results show that the working process of the test platform system is simulated expediently with the use of AMESim,the design of the test platform system is scientific,and the parameter setting is reasonable.
