摘　　要：轴承作为转子系统重要的支撑,其动特性直接影响舰船转子系统的性能.以往的研究中往往忽略轴承的弹性支撑效果,使得转子系统建模不真实,分析结果出现误差.为快速得到精确的轴承动特性系数,文中基于有限差分法和压力扰动法,求解滑动轴承动特性系数;根据相关经验公式,求解滚动轴承动特性系数;基于VC和MATLAB的混合编程,利用Matcom 4.5编译器,开发了一个通用轴承动特性系数求解软件.该软件可计算多类轴承动特性系数,提高了计算效率,占用内存少,使用方便,为设计人员实现计算机辅助设计提供支撑,为轴承及转子动力学的研究提供参考.As an important support in a rotor system,bearing has a dynamic characteristic that directly affects the performance of the rotor system of a ship. Previous studies often ignore the effect of elastic support bearings,making the rotor system modeling untrue and the results erroneous. In order to quickly get the accurate coefficients of bear-ing dynamic characteristic,in this article,based on the finite difference method and the pressure perturbation method,the dynamic coefficient of sliding bearing was obtained,and the dynamic coefficient of rolling bearings was obtained according to the relevant empirical formula. Based on the mixed programming of VC and MATLAB, using Matcom4. 5 compiler,a common bearing dynamic coefficient solving software has been developed that calcu-lates the main parameters of static and dynamic properties of the bearing. The software,of small footprint,compu-tationally efficient and easy to use,can calculate the dynamic coefficient of many types of bearings,providing a support for designers to realize computer-aided designs and reference for the bearing and rotor research.
