1.Two-years studying in 大都会怎样赚洗码费 as a visiting student researcher

留学单位:美国伊利诺伊大学厄巴纳-香槟分校
留学时间:2018.11~2020.11
Abstract:

In the past two years, Mr. Bin Fang was supported by CSC and performed his research work as a visiting student supervised by Prof. Alexander F.Vakakis and Lawrence A.Bergman at the Department of Mechanical Engineering, University of Illinois Urbana-Champaign, USA. His research interests mainly focus on the nonlinear dynamic analysis of the bearing-rotor system and non-smooth targeted energy transfer of the complex nonlinear system. In the presentation, Mr. Bin Fang will share his research and studying experience during the past two years in the US. In addition, the living and cultural experience will also be presented.

Title: Study on the Dynamic Response of an Unbalanced Rotor System Supported by Ball Bearings
Authors: Bin Fang*, Jinhua Zhang, Ke Yan, Jun Hong

Abstract: This paper proposed a new four-degree-of-freedom dynamic model of the bearing-rotor system based on ball bearing without Raceway Control Hypothesis, and both the inertia forces of balls and the tilting motions of rotor are fully considering in the calculation of restoring forces and moments of ball bearings. Then the dynamic model is solved by the fourth-step Runge-Kutta method, and the dynamic responses of rotor system including the displacement, velocity and center orbits are obtained, and the influences of rotating speeds, eccentricity and symmetry of rotor are studied and analyzed. The results show that both the varying compliance of ball bearing and rotor eccentric force have a great influence on the dynamic responses and motion patterns of bearing-rotor system, and the titling motion of bearing-rotor should be considered in the analysis of asymmetric rotor or the symmetric rotor under some specific conditions.
