| 摘 要： | 基于三维离散斜齿轮传动模型、在轴结构有限元模型、轴承弹性和齿侧间隙的基础上,建立了一个三轴斜齿轮传动转子系统的动力学模型。通过牛顿-拉夫逊法(Newton-Raphson)和非线性瞬态解方法预测了系统的强迫振动。由一台斜齿轮-轴-轴承系统组成的压缩机的试车验证了模型的有效性。结果表明,模型计算结果与试车结果吻合,给齿轮驱动的转子系统设计及故障诊断提供了理论依据。

| Abstract: | A dynamic model of a three-shaft helical gear rotor system formed by three flexible shafts is proposed. The model consists of a finite element model of shaft structures combined with a three-dimensional discrete model of helical gear sets. Bearing flexibilities are included in the model as well. In this study the contact between teeth caused by the backlash is considered. The nonlinear transient solution and the Newton-Raphson Method are used to predict forced vibrations of the system.
