This paper presents a FMEA method based on model dynamic simulation. Firstly, the functional block diagram of the system is built according to the characteristics of the airborne system, failure rate is added to the traditional functional module and the modeling of the inner behavior of the functional module is described in detail. Secondly, the dynamic running process of the system is simulated through dynamic simulation of discrete events to find out the failure states of the system and the probability of their occurrence. Finally, FMEA can be made and form can be filled base on failure state and probability of occurrence obtained from dynamic simulation. This paper solves the problems of the traditional FMEA method which can’t analyze the temporal logic analysis and the failure analysis of combined functions.
