A novel health probability for structural health monitoring

A novel structural health monitoring strategy is proposed in this paper. A baseline model between the operating parameters and measurement features is established firstly to generate the baseline working feature and validated. Then a tolerance range of deviation of practical working features from the baseline model is computed based on normal distribution. Furthermore, health probability is defined as the proportion of the number of working status in the corresponding tolerance range. Finally, the effectiveness of such novel structural health monitoring strategy is validated by simulation study and experimental work.
