【摘要】 交互作用是振动故障的真正终极原因。振动故障诊断既要研究信息,也要研究关系。本文从理论分析和工程实践中总结出,机械振动故障诊断应从局部诊断向系统诊断发展,即通过研究机械系统本身及其与输入输出及环境的相互作用来分析故障的初始原因和预测产生故障产生的条件。这可为为根治维修、故障自愈等预防工程提供技术支持。故障自愈调控是在机械系统运行中实时监测分析可能产生故障的条件及早期故障征兆,采用诊断预测、智能决策和主动控制方法使机械系统不具备产生故障的条件或自行将故障消除在萌芽中。本文简述了故障自愈调控原理及其工程应用实例,论述了故障自愈可提供新的安全监控预防故障的科学手段,是自主创新的重要方向,具有广阔的发展前景。机械振动状态是科学维修决策的重要依据,本文通过数字化远程监测诊断系统及智能维修系统的开发及工程应用,论述了基于振动监测诊断的维修与安全保障信息化智能化,是预防事故和减免维修的减灾增效工程,必将成为维修能力建设的核心。这是用知识和信息技术改造传统制造业和促进信息行业大发展的必然趋势,也是企业提高国际竞争力的重大举措。更多还原

【Abstract】 Interaction is a final root cause of vibration faults. The research of vibration faults not only includes the information, but also the interrelation. This paper drew a conclusion that faults diagnosis of machinery vibration should be extended from partial diagnosis to system diagnosis, through theoretical analysis and engineering practice. That is, to analyze the original cause of faults and to forecast the condition of faults occurred, through research on the machinery system itself as well as the interaction between it and input, output and environment. It can provide technical support for preventive engineering, such as radical maintenance and faults self-recovery. The definition of fault self-recovery regulation (FSR) is that by real-time monitoring and analyzing the possibly fault-causing conditions and early fault symptoms during operation of an equipment system, through diagnosis and prediction, intelligent decision making and active control, the preconditions of a fault can be eliminated, or the fault can be automatically terminated at its beginning stage. The theory and the engineering practices of fault self-recovery regulation were described briefly in this paper. Moreover, it is discussed that fault self-recovery regulation can provide new safety monitoring and preventing methodology. For the reason, it is the direction of independent innovation with splendid development foreground. Machinery vibration condition serves as an important foundation for scientific maintenance decision-making. This paper discussed the informationization and intelligentization of maintenance and production safeguard, on the basis of vibration monitoring and diagnosis. It is a disaster reduction and efficiency enhancement project to prevent accidents and minimize maintenance. Therefore, it still definitely becomes the cone of maintenance ability building. It necessarily complies with the trend to improve traditional manufacturing industry by knowledge and information technology, and accelerate the development of information industry. Meanwhile, it is also a significant measure for enterprises to enhance international competitiveness.更多还原
