摘要
建立内部激励及外部激励共同扰动下的单级齿轮系统刚体啮合耦合振动分析数学模型,以同步双驱动的多级混合齿轮减速器为研究对象,利用ADAMS动力学仿真平台,添加由轮齿间啮合刚度、阻尼系数及轮齿间摩擦等内部激励计算得到的Impact碰撞函数,并考虑同步驱动时波形负载的外部激励影响,完成减速器动力学模型建立和仿真。对关键零部件进行时域动力学仿真并进行FFT变换,得到轮齿间啮合力的时域及频域动力学曲线图,由分析结果可知,仿真值与理论值吻合度较高。
By establishing the coupled vibration model of single stage gear transmission and taking a synchronous driven multistages gear reducer as researched object,with the internal incentive including mesh stiffness,damping coefficient and internal friction and external stimulus of waveform load into consideration,the dynamic model and simulation is completed.With the dynamic research on implemented key parts and FFT transform added,the curves of meshing force to time and frequency is obtained,fitting greatly between the simulation value and theoretical value.
