Abstract

The invention discloses a fluid film lubrication damping technical test platform, relates to a test instrument in the field of fluid lubrication, and particularly relates to a test platform for researching of fluid film lubrication damping characteristics. The fluid film lubrication damping technical test platform comprises a foundation platform, a vibration exciter support, a test piece support assembly, vibration exciters and an oil drum set. The vibration exciter support and the test piece support assembly are mounted on the upper portion of the foundation platform; the vibration exciters are suspended on the upper portion of the vibration exciter support through bolts; the oil drum set is fixedly mounted on the test piece support assembly. The fluid film lubrication damping technical test platform has advantages of novel structure, convenience in installation and maintenance, high reliability, high automation degree and the like and surely has a positive promotion effect on fundamental research and development of the sliding bearing and aerospace fluid film lubrication damping industry after being marketed.

Description

technical field [0001] The test platform for fluid film lubrication and damping technology of the present invention relates to a test device in the field of fluid lubrication, specifically a test bench for studying the characteristics of fluid film lubrication and damping. Background technique [0002] Fluid film lubrication and damping technology is widely used in gas turbines and other high-speed rotating machinery, such as squeeze oil film dampers for aero-engine vibration damping components, which have simple structure, convenient manufacture and remarkable vibration damping effect. At present, there are relatively systematic theoretical research methods for fluid film lubrication and damping technology, and further research is needed on the lubricant film rupture boundary, bubble formation mechanism, and boundary control technology. [0003] The test platform for fluid film lubrication and damping technology can provide experimental basis for the research on the mechani...
