Abstract:

The long-term storage equipments, represented by missiles, are characterized by long-term storage, several times of testing and usage for once. Assessing the health condition timely has an important significance. According to the reliability changes of equipment, a real-time health condition assessment model based on time correction and D-S evidence theory is put forward. The health condition is measured on a scale of 1 to 5. Testing values are compared with the last non-fault testing values, the past non-fault average testing values and the standard testing values. Then these values are corrected timely and combined by D-S evidence theory so as to realize real-time health condition assessment. At last, the model is applied to a certain type of equipment. The instance shows that this model improves the performance in the field of assessing health condition for long-term storage equipments.
