Abstract

Ships sailing on the sea, due to the uncontrollable environmental impact of wind and waves, will make a variety of complex periodic rocking motions, such as longitudinal and transverse rocking motions of greater impact. This study based on the simulated sea condition more freedom to swing test bench, simulate the swing of the ship on the sea, the eddy current sensor device on the rotor bearing, put on the laboratory bench, the rotor bearing device using programmable loader to control the rotor speed, using LMS_Test. Lab modal test instrument analysis software for data acquisition, signal analysis. In this paper, the influence of the periodic speed on the dynamic characteristics of the bearing rotor system under pitching condition and the influence on the distance acceleration of the system under different conditions are mainly analyzed.
