Abstract: The vibration mode and natural frequency of machines are closely related to its resonance phenomena. In order to improve the quality of edging, and reduce vibration or avoid resonance, dynamic characteristics of the grinding equipment was analyzed by finite element analysis software ANSYS. By the experimental method, the joints’ kinetic parameters were obtained and detail research on the way of creating joint’s dynamic model was conducted. Model analysis of rigid connection and combined face spring damper connection model was carried out. Test datas were compared with the results of finite analysis. The result shows that the finite element analysis results of combined face spring-damping connection are in good agreement with experimental results. The response state was simulated in actual work by harmonic, and probable reasons for uneven edging were given.
