摘要
为了模拟工程应用中斜齿轮转子系统的动力学特性,考虑齿轮齿面刚度分布场、传递误差分布场、啮合过程中啮合刚度、摆动刚度和刚度中心等参数,建立了通用的斜齿轮集中质量模型.将该模型与转子系统有限元模型进行了耦合,得到了斜齿轮转子系统有限元模型.最后,以一对斜齿轮转子系统为例,分析了该系统的振动响应特性.研究结果表明:该模型能够有效精确地模拟齿轮之间的啮合.通过对啮合力响应进行傅里叶分析,表明齿轮1倍啮合频率对系统响应影响最大,而其他频率对系统振动响应影响较小.
Taking the tooth stiffness distribution, transmission error distribution, translational stiffness, twist stiffness and the center of stiffness into account, a dynamic model for general helical gear pairs is developed. Then the rotors and bearing flexibility are introduced to the model, and a finite element model for the rotor system of helical gear is determined. Finally, dynamic responses are analyzed based on the gear rotor systems. The results show that the model is effective and accurate for general helical gear rotor systems. Moreover, through studying the fast Fourier transform of the dynamic mesh force, the 1 x mesh frequencies of the system has a main influence on the response the rotor system.
