以一种星型轮系人字齿轮传动系统为研究对象,为了查找系统共振原因,建立模态分析3D有限元模型,分析了星型轮系人字齿轮传动系统的模态特性。根据星型轮系试验测试结果,发现转频激励和啮频激励引起的共振是系统振动幅值的主要组成部分;根据这一现象,基于齿轮啮合刚度矩阵,建立3D有限元模型,分析了系统的模态特性。结果表明,仿真所得转频共振模态和啮频共振模态与试验均具有唯一对应性,啮频共振模态主要表现为内齿圈的5节径振型耦合齿轮副扭转振型。该有限元模型的建立为星型轮系人字齿轮传动系统的共振预测和共振原因分析提供了有价值的参考方法。
A herringbone gear transmission system with star gear train is taken as the research object. In order to find the cause of system resonance, a modal-analyzing 3D finite element model is established to analyze the modal characteristics of herringbone gear transmission system of star gear train. Firstly, according to the experimental results of star gear train, the resonance caused by rotational frequency excitation and meshing frequency excitation is the main part of the vibration amplitude of the system. According to this phenomenon, a 3D finite element model is established based on the meshing stiffness matrix to analyze the modal characteristics of the system. The results show that the rotational frequency resonance mode and meshing frequency resonance mode obtained by simulation are uniquely corresponding to the experiment data, and the meshing frequency resonance mode is mainly represented by the fifth pitch diameter vibration mode of the inner gear and the torsional vibration mode of the coupled gear pair. This finite element model provides a valuable reference method for resonance prediction and resonance cause analysis of herringbone gear transmission system with star gear train.
