摘要

对某大型船用齿轮箱的动态特性进行分析，将系统分为传动子系统和结构子系统，通过支撑轴承把两个子系统耦合起来，建立齿轮-轴-轴承-箱体耦合系统三维有限元模型。在研究斜齿轮接触线变化规律基础上，提出了一种计算斜齿轮时变刚度的方法。在考虑传动子系统内部激励和外部激励的影响下，对系统动态特性进行了数值仿真，得出了结构子系统各点的振动位移、速度等动态评价指标，以及系统的结构预估噪声，为船用齿轮箱系统动态性能优化提供了理论依据。

Abstract

In this paper, a 3-D finite element model of a gear-rotor-bearing-box coupling system is developed by coupling transmission subsystem and structure subsystem with the support of bearing for the analysis of the kinetic characteristic of large burden marine gearbox. Based on the research on the change of contact line of helical gears, a method of calculating the time-variant stiffness is proposed. Considering the effect of internal and external excitation on the transmission subsystem, its kinetic characteristic is dealt with by numerical simulation. The kinetic evaluating indexes of structure subsystem, such as vibration displacement and velocity, and the structure preestimated noise are obtained. The research results lay down a theoretical basis to optimize the dynamic performance of large burden marine gearbox.
