以有限元分析理论为基础，借助于大型结构分析软件ANSYS，对锯切过程中受高频周期脉冲激励锯片的动态响应进行了计算，并对锯片上不同点的速度及加速度港进行了分析。发现锯片上各点的响应不但不相同而且差别很大，响应的最大值出现在锯片与工件接触的地方，且发生在齿通频率附近，夹盘上各点的响应比锯片部分的小得多。因此在锯切过程中，锯片外沿既是产生噪声的主要部位也是锯片容易疲劳破坏的地方。
Based on the finite element analysis theory, the dynamic response of saw blades excited by high frequency periodic pulses in sawing process was calculated by means of ANSYS, a large-scale structural analysis software. The different speeds and acceleration ports on saw blades analysis. Found that the response of each point on the saw blade not only different but also very different, the maximum response appears in the saw blade and the workpiece contact place, and occurs in the tooth near the frequency, the response of each point on the chuck than the saw blade part Much smaller. Therefore, in the sawing process, the outer edge of the saw blade is not only the main part of the noise is also easy to fatigue saw blade damage.
