摘　　要：针对金刚石锯片锯齿径向槽部分在锯切力作用下出现变形及局部应力集中的问题,利用有限元软件ANSYS Workbench,通过设计正交试验对径向槽各参数进行了仿真研究。分析了径向槽各参数对锯齿变形量以及等效应力、径向应力、切向应力的影响大小,得出了最优径向槽参数组合,并对结果进行了实验验证,以此对径向槽参数进行了优化设计。研究结果表明:径向槽参数中径向槽底孔半径对锯片变形影响最大,深度对锯片变形影响最小;径向槽宽度对锯片的各应力的影响最大,深度对各应力的影响最小;等效应力、最大切向应力、最大径向应力最优时,槽底孔半径R取4 mm,径向槽宽度B取3 mm,径向槽深度H取17 mm。Aiming at the problem of deformation and local stress concentration in the sawtooth radial groove of diamond saw blade under sa wing force the parameters of the radial groove were simulated by using ANSYS Workbench and orthogonal test. The influence of the parame ters of the radial groove on the sawtooth deformation equivalent stress radial stress and tangential stress was analyzed and the optimal pa rameters of the radial groove were obtained. Finally the experimental results were verified to optimize the parameters of the radial groove. The results indicate that the radius of the bottom hole of the radial groove has the greatest effect on the deformation of the saw blade and the depth has the least effect on the deformation of the saw blade. The width of the radial groove has the greatest effect on the stress of the saw blade and the depth has the least effect on the stress. When the equivalent stress the maximum tangential stress and the maximum radial stress are optimal the radius of the bottom hole R is 4 mm the width of the radial groove B is 3 mm and the depth of the radial groove H is 17 mm.
