摘要
Abstract
The state of shafting alignment can directly affect the shafting vibration. Analyzing the influence law of the shafting alignment is of great significance for the recognition and effective control of the abnormal vibrations. In this paper, the nonlinear dynamic model related to stern bearing elevation was used, and the propeller imbalance whirling was considered. On this basis, a mathematical model for nonlinear dynamic analysis of the shafting system was established by means of the finite element method. The nonlinear dynamic response of the shafting system was solved. The relation between the stern bearing elevation and the vertical bending vibration was analyzed. This work has provided a reference for improving the status of bearing elevation and reducing the lateral vibration.关键词
