耐冲击型金刚石圆锯片锯切受力的数值模拟(二)——以新型半圆形水槽锯片为例

建立耐冲击型金刚石锯片锯切受力的有限元分析模型，围绕新型半圆形水槽和传统U型水槽的2种齿形结构，以数值模拟对比研究金刚石圆锯片的锯切受力。仿真结果表明:在承受相同载荷的情况下，新型半圆形水槽锯片较传统U型水槽锯片在锯切受力时的变形、应力方面都得到了明显改善，其变形量减少11.56%，第一、第三主应力分别降低24.04%和34.19%，因而其承受大载荷和耐冲击性能良好。 

Finite element simulation of sawing force for impact-resistant diamond saw blades——Take circular saw blades with new semi-circular sink tooth shape as an example

The finite element analysis model of the cutting force of the impact resistant diamond saw blade was established.The numerical simulation and comparative study of the cutting force of the diamond circular saw blade were carried out on the two kinds of tooth structures,with the conventional U-shaped sink and the new semi-circular sinktooth shape.The simulation results show that under the same load,the deformation and stress of the saw blades with new semi-circular sinktooth shape are significantly improved compared with that of the traditional U-shaped sink.The deformation of the saw blade is reduced by 11.56%,the first and third principal stresses are reduced by 24.04%and 34.19%respectively.Therefore,it has good performance of bearing large load and impact resistance.
