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。
A mathematical model of rigid body meshing coupled vibration analysis of single-stage gear system with internal disturbance and external disturbance was established. Taking synchronous dual-drive multi-stage compound gear reducer as research object, ADAMS dynamics simulation platform was used to add the meshing between teeth Stiffness, damping coefficient and inter-tooth friction and so on. The dynamic model of reducer is built and simulated considering the influence of external excitation of the waveform load when driving synchronously. Time-domain dynamics simulation and FFT transformation of key components are performed to obtain the time-domain and frequency-domain dynamics curves of the intermeshing forces. The analysis results show that the simulation values are in good agreement with the theoretical values.
