Abstract

To solve the problem of system-level thermal effect and condition assessment, the dynamic reliability assessment model of the structural and functional components is established. The continuous process simulation is combined with discrete event simulation. The temperature field, deformation field and stress field is calculated by continuous process simulation, and the reliability index, such as the health status is calculated by discrete event simulation. Meanwhile the efficient and collaborative algorithm of the model is studied. On the basis of the above analysis method, the multiple component system is established and the cycles directed energy boundary conditions is applied. The state of the system is obtained by simulation. The analysis results show that the health state of the system decreases faster with the increase of power density. When the power density increases from 2W/cm2 to 8W/cm2, the decline rate of health state of the system increases by 1 times. This analysis method can provide a technical basis for the study of system irradiation effect.
