一、引言转子不对中一直是引起旋转机械设备振动故障的主要原因之一。美国和日本等国专家在调查和分析振动故障资料后认为，迫使设备停机检修的60％的故障是因不对中引起的。所以如何做好转子热态合理对中工作，已成为亟待解决的问题，目前对于各类旋转机械开展对中研究发展是?
I. INTRODUCTION Rotor misalignment has been one of the main causes of vibration problems in rotating machinery and equipment. After investigating and analyzing the vibration fault data, experts from the United States, Japan and other countries considered that 60% of the failures that forced the equipment to shut down for maintenance were caused by misalignment. Therefore, how to make the rotor hot and reasonable to work in alignment has become an issue to be solved urgently. At present, is there any research on the development of various types of rotating machinery?
