A simulation-based method for EMR assessment of aviation electronic products

摘要

With the application and development of electronic devices, the electromagnetic energy in our surrounding space is gaining rapidly. Especially for those aviation electronic products in the limited space, their characters, such as variety, high density, sensitivity and power, make them susceptible to electromagnetic interference. Traditional electromagnetic compliance (EMC) analysis focuses on EMC design, targeting passing the EMC tests. However, there are few researches on EMC reliability or even the reliability index. Concerning this issue, this paper puts forward to a complete theory to assess the electromagnetic reliability (EMR) of the aviation electronic product. It combines stress-strength interference (SSI) model, probabilistic physics of failure (PPoF) method and simulation analysis, which provides theory support to solve the EMC problems and improve its reliability.
