| Abstract: | To investigate the effectiveness problem of stochastic assumption in deterioration failure analysis of mechanism equipment,a kind of simulation method based on Gamma bridge sample is presented in this paper.A practical example is put forward to compare the ferrography data of diesel oil engine to the data path from the simulation result of Gamma process, which validate the effectiveness of Gamma process to describe the monotonous deterioration process. |
