Structural optimization study ofФ350 mm diamond saw blade

金刚石锯片在使用过程中的受力会导致金刚石颗粒脱落,从而降低刀具使用寿命。针对此现象,研究改变刀具结构以改善金刚石锯片工作时的受力情况。以Ф350 mm金刚石锯片为研究对象,应用有限元软件ANSYS Workbench,对其进行建模和静力学分析,从改变节块数量、钥匙槽宽度、钥匙槽深度、钥匙孔直径、降噪孔直径等方面对锯片进行结构优化。对比优化模型与原模型的应力云图,优化模型的最大等效应力减少了27.5 MPa,减少量达43.4%。结果表明,优化后的金刚石锯片在相同切削条件下所受应力情况得到明显改善。

The force on the diamond saw blade in use will cause the diamond particles to fall off,thus reducing the service life of the tool.In view of this phenomenon,the research is carried out on how to change the tool structure to improve the stress of diamond saw blade during operation.Ф350 mm diamond saw blade is taken as the research object.The finite element software ANSYS Workbench is used to model and analyze the statics.The saw blade structure is optimized from changing the number of segments,the width of the key slot,the depth of the key slot,the diameter of the key hole,and the diameter of the noise reduction hole.By comparing the stress nephogram of the optimized model with that of the original model,the maximum equivalent stress of the optimized model is reduced by 27.5 MPa,reduction of 43.4%.The result shows that the stress of the optimized diamond saw blade is obviously improved under the same cutting condition.
