故障预测和健康状态管理(PHM)技术是新一代装备的先进测试、维修及状态管理技术,成为新装备设计和使用中的一个组成部分。将时间分形概念引入到PHM的故障或寿命预测中,在时间分维上寻找到电子装备整体与部分间的相似关系,表明分形维数的改变与系统状态的劣化有对应关系,系统临近破坏分形维数就降低。降低了装备寿命预测对资源要求,促进了PHM和分形本身的发展。
Fault Prediction and Health Management (PHM) technology is a state-of-the-art test, repair and condition management technology for next-generation equipment that has become part of the design and use of new equipment. The concept of time fractal is introduced into the fault or life prediction of PHM. The similarity between whole and part of electronic equipment is found in the time dimension, which shows that the change of fractal dimension has a corresponding relationship with the deterioration of system state. The number of dimensions is reduced. Reduced resource requirements for equipment life prediction and promoted the development of PHM and fractal itself.
