一种压力容器缺陷剩余寿命预测的新方法

New method of the residual life prediction of pressure vessel defect

通过基于空气动力压力容器安全评定的缺陷失效路径与失效速率的仿真系统,来寻找裂纹缺陷在安全临界域速率拐点及a_N的临界值,进而建立一种全新的评估压力容器剩余寿命的理论判据.

Using the safety evaluation simulation system for the failure rate and paths of the crack on the aerodynamic pressure vessel to find the inflection point of the failure rate in safety critical region and the threshold of aN and establish a new theory criterion for pressure vessel residual life prediction.
