%X 为研究单级齿轮减速器箱体的动静态特性，避免产生共振。建立了齿轮箱箱体的三维模型，利用ANSYS Workbench软件进行静力学分析和模态分析。通过计算得到箱体的最大应力、最大变形分布云图、固有频率以及相应振型。在模态分析的基础上，对减速器箱体进行谐响应分析，得到位移与频率响应曲线。结果表明：箱体强度在许用范围之内，箱体输出轴轴承孔部位为受力薄弱部位，易发生共振的激励频率为1297.7 Hz。以上工作为减速器的结构优化设计、振动问题的研究分析带来了新的见解。<br />
In order to study the dynamic and static characteristics of single-stage gearbox case to avoid resonance. A three-dimensional model of the gearbox case was established, and the static analysis and modal analysis are carried out using ANSYS Workbench software. The maximum stress, the maximum deformation distribution cloud, the natural frequency and vibration type of the box are obtained by calculation. On the basis of modal analysis, the harmonic response analysis of the gearbox is carried out to obtain the displacement and frequency response curves. The results show that the strength of the case is within the permissible range, the output shaft bearing hole part of the case is the weak part of the force, and the excitation frequency of resonance is 1297.7 Hz. It brings new insights into the structural optimization design of gearboxes and the research and analysis of vibration problems.
