摘　　要：金刚石锯条锯切石材过程中,存在着严重的振动问题。为研究金刚石锯条的动态性能,通过ANSYS软件建立金刚石锯条三维参数化模型,并利用有限元软件进行模态分析,得到固有频率和振型,通过采用试验法对金刚石圆锯条进行模态试验。对比两种结果误差较小,利用该模型可代替试验对金刚石圆锯条进行模态分析,为进一步研究锯条的振动稳定性问题打下了基础。There are serious vibration problems in the sawing process of diamondr saw blade. In order to study the dynamic characteristics of diamond blade, the 3d parametric model and modal analysis was conducted by ANSYS software, at the same time the natural frequency and the principal mode were analyzed. And the modal test is carried out using the hammer vibration. Comparing the result of two methods, the results of finite element modal analysis mapped meshing is closer to the experimental results. Using this model instead of testing parametric modal analysis, and it can provide a foundation for further study on stability of diamond saw blade.
