Abstract
On condition that pans and tilts, ship bearing rotor system stability and security, as the change of ship swaying amplitude have influence, based on independent research and development of guangzhou maritime college design of vertical and horizontal swing test bench, simulate the real working condition of ships at sea, in the performance of bearing rotor system under rolling condition were studied. LMS_TEST. LAB modal tester software was used to analyze the dynamic characteristics and collect the experimental data of the bearing rotor system for analysis and research. In this paper, the influence of period and amplitude on the dynamic characteristics of the bearing-rotor system and the influence on the axis trajectory of the bearing-rotor system under different working conditions are analyzed mainly under the rolling condition.
