基于PHM的复杂机电系统健康管理技术研究

随着社会生产力的快速发展,复杂机电系统作为工业自动化领域重要组成之一,智能化、自动化程度越来越高,也对维修保障能力提出了更高要求。目前我国大多数复杂机电系统仍然以定期维修和故障维修为主,维修技术已经显著落后于设备发展水平。本文基于故障预测与健康管理技术,在剖析复杂机电系统常见故障模式的基础上,研究了复杂机电系统健康管理系统的层次架构、功能组成、技术途径,为视情维修保障模式在复杂机电系统中的应用方式方法进行了有益探索。

Research on Health Management Technology of Complex Electromechanical System Based on PHM

Due to the rapid development of social productivity, the complex electromechanical system has become one of the important components of industrial automation domain. The complex electromechanical system is becoming more advanced in terms of intellection and automation. Consequently the demand in maintenance ability has been raised to a higher level. Whereas the major domestic complex electromechanical systems sustain a periodic maintenance and posterior maintenance mode currently, which indicates the development of maintenance technique is clearly fall behind the development of equipment. This paper is based on fault prediction, prognostic and health management (PHM) technique and combined with the analyses of common fault patterns in complex electromechanical system, studied the health management system of complex electromechanical system in terms of hierarchy, functional composition and technical approach. It provides positive discoveries for on-conditional maintenance mode applying to complex electromechanical systems.
