FMIS METHOD FOR POWER SUPPLY MODULE OF AVIATION PARAMETER PROCESSING DEVICE

摘要

An FMIS method for the power supply module of an aviation parameter processing device, the method comprising four steps: step 1, determining a key component on the power supply module of the aviation parameter processing device; step 2, determining the failure mode of the key component; step 3, simulating the transient circuit of the power supply module under normal conditions; and step 4, simulating the transient circuit of the power supply module under failure condition. Based on a stress simulation method and a failure mode and injection technology, the present invention determines the failure mode of the power supply module of the aviation parameter processing device, and quantitatively obtains a circuit output under the failure mode, thus providing basis for a designer to evaluate the effect of the failure mode and determine the hazardness thereof, and also providing basis for design improvement of the power supply module. The present invention has better practical value and wide application prospect in the technical field of product reliability simulation.
