摘　　要：通过ANSYS建立了锯片-辅助控制器模型,并运用谐响应分析方法,主要分析了有无辅助控制器、不同刚度辅助控制器对锯片振动的影响。最后通过测量锯片-辅助控制器的系统幅频特性来验证仿真分析结论。仿真及实验结果表明:外加辅助控制对锯片在共振频率上的振动抑制效果相当显著,对非共振频率点上的振动也有一定的抑制效果。In this experiment,a model of diamond circular saw blade with auxiliary controller was built by simulation software ANSYS. Influences of the presence and stiffness of the auxiliary controller on circular saw blade were analyzed by harmonic response analysis. The amplitude-frequency characteristics of circular saw blade with auxiliary controller system were measured to verify the analysis conclusions. The simulation and experimental results showed that the vibration suppression effect of the auxiliary controller for the circular saw blade was significant on the resonant frequency,while the effect was weaker on the other frequency.
