机器故障诊断技术是近二十年来国际上得到较快发展的新技术,它涉及到数学、物理、化学、声学等多门自然学科。美国起步最早,1961年就成立了国家机械故障研究协会(MFPC),并与宇航、航空、军工等重要部门的技术相联系,取得了明显的经济效益。其它一些工业发达国家如英国、法国、丹麦、日本、瑞典和西德也把它作为提高企业设备利用率和经济效益的根本措施之一,提出了许多诊断方面的理论,研制出不少故
Machine fault diagnosis technology is a new technology developed rapidly in the past two decades in the world. It involves many natural disciplines such as mathematics, physics, chemistry and acoustics. The United States started as early as 1961 and established the National Association of Mechanical Failure Research (MFPC). It has also achieved significant economic benefits in connection with the technology of major sectors such as aerospace, aviation and military. Some other industrialized countries such as Britain, France, Denmark, Japan, Sweden and West Germany also put it as one of the basic measures to improve the utilization rate and economic efficiency of enterprises. They put forward many diagnostic theories and developed many
