预测高温承压部件的持久寿命及其可靠度。

Abstract

Based on the endurance test data of high temperature parts

a regression processing has been carried out by using the certain creep rupture extrapolation equation

and then several persistent lifes have been simulated and produced by means of Monte Carlo method and the strong calculating function of MATLAB. On the basis of random dispersivity concerning the persistent life and its statistical behavior

the persistent life of high-temperature pressurized parts and their reliability can be predicted.
