Study on system status evaluation method

摘要

To solve the problem of system-level thermal effect and condition assessment, the dynamic reliability assessment modelof the structural and functional components is established. The continuous process simulation is combined with discreteevent 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 andcollaborative algorithm of the model is studied. On the basis of the above analysis method, the multiple component systemis established and the cycles directed energy boundary conditions is applied. The state of the system is obtained bysimulation. 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/cm~2 to 8W/cm~2, the decline rate of health state of the system increasesby 1 times. This analysis method can provide a technical basis for the study of system irradiation effect.
