中文摘要:基于局域波分析的时频多分辨特性,提出了多尺度Hilbert谱熵的概念,并给出了多尺度Hilbert谱熵的计算方法。将其应用到往复式压缩机的故障诊断中,比较了时频熵与多尺度Hilbert熵在实际应用中的效果,证实了多尺度Hilbert谱熵能更准确地反映机组的状态。

Abstract: The conception of multi-scale Hilbert spectrum entropy (MSHSE) was proposed based on the multi-scale analysis character of the local wave method (LWM) and its calculation method was developed. MSHSE was applied to the fault diagnosis of reciprocating compressor valves. By comparing with time-frequency entropy, MSHSE is proved to be more accurate in revealing the machine status.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
