Research On Key Structural Health Monitoring Technology Of A Certain Type Of Artillery Firepower Syste

With the development of high and new technology,the functions of modern artillery are more and more diversified,and the structure is more and more complex,which poses a challenge to the stability and safety of artillery performance.The health monitoring technology of artillery system has gradually become one of the hot spots of people’s attention and research.As an important component of the artillery system,the stability and safety of the firepower system seriously affect the combat performance of the artillery.Based on the structural characteristics and failure mechanism of the firepower system,this paper studies the health monitoring technology of the key structure of a certain type of artillery firepower system.The main research contents include:(1)Analyze the composition and structure of the firepower system.The main components and their functions of the firepower system are introduced;by analyzing the common faults of the firepower system,the key structural components of the firepower system mainly studied in this paper are determined;by studying the failure mechanism of the key structural components of the firepower system,the health monitoring system is clarified Collected health monitoring parameters.(2)The changing law of the health monitoring parameters of the firepower system during the firing of the artillery is analyzed in detail,the structural characteristics and test conditions of different components are comprehensively considered,the monitoring principles and methods of the health monitoring parameters are determined,and the design principles of the health monitoring system are proposed.(3)A method for evaluating the health status of firepower systems is proposed,which combines fuzzy gray whitening weight clustering and D-S evidence theory.The health status of the firepower system is defined as four states: healthy,sub-healthy,available and faulty.First,the health status of each key structural component of the firepower system is evaluated at the first level by using the grey whitening weight clustering and DS evidence theory,and then the combined weighting is used.The overall health status of all key structural components of the firepower system is evaluated by the method and fuzzy comprehensive evaluation method.Finally,the validity and accuracy of the health evaluation method proposed in this paper are verified by experiments.(4)Based on the characteristics of health monitoring parameters and the working principles and applicable conditions of different sensors,the sensors selected for the health monitoring system are determined;starting from the functional requirements of the health monitoring system,the hardware architecture and software architecture of the firepower system health monitoring system are designed.The design mainly includes the overall architecture design of the hardware system and the circuit design of each module,and the software design mainly includes the software design of the lower computer,and the performance of the designed health monitoring system is tested and verified.
