为探究双计量板计量装药设备驱动机构的振动特性及验证是否满足设计要求，利用ANSYS Workbench 仿 真软件对其进行动态特性分析。通过有限元模态分析求取驱动机构前6 阶的固有频率及相应振型，与工作时的外部 激励频率进行对比分析，研究该驱动机构在工作过程中的共振情况。采用瞬态动力学仿真方法，对驱动机构的凸轮 进行强度分析，获得凸轮工作过程中的应力应变情况。结果表明：该驱动机构工作时在外部激励作用下不会产生共 振，满足模态设计要求，凸轮满足强度要求，可以安全工作。
In order to explore the vibration characteristics of the driving mechanism of metering charging machine with double metering plate and verify the design requirements are met, the dynamic characteristics are analyzed by using ANSYS Workbench simulation software. Firstly, the first six natural frequencies and corresponding modes of the driving mechanism are obtained by finite element modal analysis. Then, the resonance of the driving mechanism during the working process is studied by comparing with the external excitation frequency. Secondly, the strength of the cam of the driving mechanism is analyzed by means of transient dynamics simulation. And the stress of the cam during the working process is obtained. The results show that, the driving mechanism will not cause resonance under the external incentive during the working process, and it meets the requirements of modal design. Meanwhile, the cam meets the strength requirements and works safely.
