Abstract
For reliability analysis of implicit limit state function, an improved line sampling method
is presented on the basis of sample simulation in failure region. In the presented method, Markov
Chain is employed to simulate the samples located at failure region, and the important direction of
line sampling is obtained from these simulated samples. Simultaneously, the simulated samples can
be used as the samples for line sampling to evaluate the failure probability. Since the Markov Chain
samples are recycled for both determination of the important direction and calculation of the failure
probability, the computational cost of the line sampling is reduced greatly. The practical application
in reliability analysis for low cycle fatigue life of an aeronautical engine turbine disc structure under
0-takeoff-0 cycle load shows that the presented method is rational and feasible.
