—During mechanical products are in the process of
testing or running, a number of key components will be wearing
and aging, resulting in some sizes or gaps change. This kind of
phenomena can be called the structural degradation. In order to
obtain the degradation data, we need to dismantle and inspect
the product in a planned way, which is usually a very complex
work. However, it’s seldom to carry out the research work
based on structural degradation data in the research field of
reliability assessment and life prediction. In this paper, the
structural degradation data are described as a linear stochastic
process model, considering the failure mechanism of the
product, the reliability function can be obtained. At last a
numerical example of a marine steam turbo-generator (MSTG)
is given to illustrate the efficiency of this model.
