Application of Reliability Simulation Based on Failure Physic in Avionics Device

摘要: 文章针对航空电子产品的可靠性设计，介绍了一种基于故障物理的可靠性仿真分析方法，这种方法是在对有关物理现象及失效机理深入认识的基础上，利用仿真和推导定量模型来进行故障预计。本文采用该方法对某型号飞机的飞行控制计算机进行了故障预计，通过了解可能发生的失效模式及其机理，发现产品或现有技术中潜在的问题和薄弱环节，并用来指导产品设计及提高产品的可靠性，最终得出基于故障物理的可靠性仿真分析对于提高航电设备可靠性设计具有积极作用的结论

Abstract: Reliability simulation based on failure physic is introduced for improving reliability of avionic device. Failure prediction is achieved based on simulation method and quantitative model. The failure prediction of flight control computer was preformed by using this method. And the defects in technology were found which could be used to improve reliability of product. So we come to a conclusion that reliability simulation based on failure physic can effectively advance reliability of avionics device.
