Mechanical Products Reliability Assessment Based on the Structural Performance Degradation Data

Wang Qiang, Feng Jing, Sun Quan, Pan Zhengqiang, and Meng Jieru
Abstract—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.

Index Terms—Reliability assessment, life prediction, structural performance degradation data, marine steam turbo-generator (MSTG).
