摘要
Abstract
Shipboard electronic products have the characteristics of high reliability and long lifespan,and the fast evaluation of its reliability level is an important means to guarantee the quality.This paper provides an accelerated model construction method suitable for shipboard electronic products.Firstly,the meteorological information of the navigation sea area is collected and analyzed,and the main marine environment and stress value are quantified.Then,it carries out characteristic analysis and fault mechanism analysis of shipboard electronic products,gives the typical failure modes and their sensitive stresses of electronic products.Finally,the construction method of the acceleration model based on fault physics is given,and the acceleration stresses of low temperature of-65℃,high temperature of 90℃and temperature change rate of-15℃/min are determined,and the acceleration factor is 5.6,which provides a reference for rapidly evaluating the life index of shipboard electronic equipment.关键词
