Since maintenance is an important way to keep the ordnance equipment in good technical condition， reliability-centric maintenance strategy optimization has received extensive attention from experts in the industry. Based on the performance degradation law of ordnance equipment components under the condition of participating in maintenance activities，this paper studies the impact of maintenance on the performance status of the equipment. Through the equipment failure process analysis under the condition of regular maintenance，a maintenance strategy model of regular maintenance equipment is established. The effectiveness of the model is verified through the analysis of the maintenance examples of typical components.
