Comprehensive Analysis of Dynamic Characteristic Experiment and Theoretical Calculation of Marine Shafting

论述了船舶轴系动态特性的实验与理论计算的综合分析方法。用该法可通过在轴系便于设置测点处测量得的几个参数推算出整个轴系的动态特性及各个轴承的附加动态轴承负荷，并可利用实测参数对目前难以确定的原始计算参数进行必要的修正，使求得的轴系动态特性与各个轴承的附加动态轴承负荷能符合实际情况。在船舶轴系试验台上进行的实验及理论计算表明。

his paper presents a comprehensive method for analyzing dynamic characteristic experiment and theoretical calculation of marine shafting. By measuring some parameters of marineshafting which are easy to be measured, the dynamic characteristic and attached dynamic bearing loads of marine shafting can be calculated by this comprehensive method. In addition, thefirsthand data which are not easy to be determined at present can be corrected by means of thiscomprehensive method according experiment. Therfore, the dynamic characteristic and attacheddynamic bearing lOads of marine shafting which are calculated by this comprehensive methodcan be in cooformity with actual situation. The experimental research on a shafting test bed andtheoretical calculation show that this comprehensive method is correct and practicable.
