Description
technical field [0001] The invention discloses a rotor support system used for performance testing of high-speed water-lubricated dynamic pressure bearings, which belongs to the technical field of mechanical design. Background technique [0002] The dynamic parameters such as the oil film stiffness and damping of the sliding bearing directly affect the dynamic characteristics of the rotor system, and have an important impact on the rotor stiffness, stability, and critical speed. Since there are many factors affecting the dynamic parameters of the oil film, it is essential to test and study the dynamic parameters in the study of sliding bearings. Water-lubricated dynamic pressure bearing has many advantages such as good high-speed performance, low cost, no pollution, and simple peripheral equipment. It is one of the main directions in the field of bearing research at present. [0003] The research and development of water-lubricated bearing dynamic performance testing device...
