Embodiment

[0162] Taking a high-voltage transmission line system as an example, the system maintenance effect modeling is completed, and the application analysis is carried out.

[0163] The required parameters in the model are as follows:

[0164]

[0165] After the above steps 1, 2, and 3, the system maintenance effect model is established, and the reliability of the system can be obtained from the formula (4). In the above reliability function, for the reliability solution after multiple preventive maintenance before time t Because there are many kinds of convolutions, it is difficult to simplify. Therefore, this paper uses the Monte Carlo simulation method to solve the reliability of the system. The specific method is as follows Figure 7 .

[0166] Such as Figure 8 Shown is the reliability function of the system considering the maintenance effect. Among them, Case1 indicates that only the impact of preventive maintenance work on the degradation level is considered; Case2 cons...

Abstract

The invention provides a maintenance effect modeling method considering a maintenance negative effect. The method comprises the following steps of 1, determining a system reliability model; 2, quantitatively describing a maintenance effect; 3, establishing a system maintenance effect model; 4, carrying out application and analysis of a maintenance effect model: applying the established maintenancemodel considering the maintenance effect to a maintenance decision, performing the maintenance decision on the system by adopting a maintenance strategy limited by a fault threshold, and analyzing amaintenance decision result. By means of the steps, the maintenance effect is fully considered in the maintenance modeling process, quantitative calculation and analysis are conducted, maintenance decisions are more scientific and accurate, then the optimal efficiency-cost ratio of the system is achieved, and operation and maintenance work of enterprises is facilitated.

Description

[0001] (1) Technical field: [0002] The invention provides a maintenance effect modeling method considering the maintenance negative effect, which is a maintenance modeling method which fully considers the maintenance effect for the degradation-shock competition failure repairable system. It focuses on the maintenance effect, fully considers and quantifies the correlation between various maintenance effects (positive and negative) and failure modes, and proposes a maintenance effect modeling method based on product status and a modeling idea that different maintenance activities will produce different maintenance effects. The proposed maintenance effect model can be applied to maintenance decision-making, and it has a certain effect on improving maintenance efficiency and quality and reducing maintenance risks for important systems or facilities with high reliability such as weapons and equipment, intelligent electromechanical systems, and industrial automated production systems...
