摘　　要：船舶推进轴系的校中质量是影响其安全、稳定和可持续运行的主要因素之一。现阶段用于指导工程实践的轴系校中方法大多为静态校中,如按直线校中、合理校中、轴承位置双向优化校中等。而动态校中尚处于理论研究阶段,鲜有人研究在船舶运行过程中螺旋桨水动力对轴系校中状态参数的影响。本文以某电力推进轴系为对象,通过建立该艇的桨-轴-艇体及其周围水域的三维模型,计算该艇在额定工况下运行时的螺旋桨水动力,并对比研究分析水动力对该轴系校中状态参数的影响。研究结果可为预测轴系运行动态参数和后续的轴系优化改型提供一定的参考。The alignment quality of a ship propulsion shafting system is one of the main factors affecting its safe, stable and sustainable operation. At present, the shafting alignment methods used to guide engineering practice are mostly static alignment, such as linear alignment,reasonable alignment, and bidirectional optimization alignment of bearing position. However, the dynamic alignment is still in the stage of theoretical research, and few people have studied the influence of propeller hydrodynamic force on shafting alignment state parameters during ship operation. In this paper, a motor driving shafting system was taken as the study object, the three-dimensional models of propeller-shafting-hull model and its surrounding waters of the ship were established to calculate the propeller hydrodynamic force of the ship under rated working conditions,and the influence of the force on the shafting alignment state parameters was compared and analyzed. The research results can provide some reference for predicting the dynamic operating parameters of shafting and subsequent shafting optimization and modification.
