摘　　要：振动慢剪破碎机在工作时引入主动激振。为研究其受迫振动与固有频率之间的关系,避免共振,以某振动慢剪破碎机为研究对象,运用有限元软件建模分析其计算模态,通过敲击激励实验测试其实验模态,并将计算模态与实验模态对比。表明振动慢剪破碎机的前8阶固有频率集中在26.86 Hz到259.30 Hz之间;破碎机的主要变形部件集中在板簧、大齿轮、机架、内锥四部分。研究结果为振动慢剪破碎机的振动电机和三相异步电机选取提供参考。The vibration slow shear crusher introduces active excitation during operation. In order to study the relationship between forced vibration and natural frequency and avoid resonance, a vibration slow shear crusher is taken as the research object, and finite element analysis software is used tomodel.The calculated natural frequency is analyzed, the experimental natural frequency is tested by tapping experiments, and the calculated modality is compared with the experimental modality. It shows that the first 8 natural frequencies of the vibration slow shear crusher are concentrated between 26.86 Hz and 259.30 Hz;the main deformation parts of the crusher are concentrated in the four parts leaf spring, the large gear, the frame and the inner cone. The research results provide reference for the selection of vibration motor and three-phase asynchronous motor of vibration slow shear crusher.
