| 摘 要： | 金刚石圆锯片锯切过程中，普遍存在严重的振动问题。采用随机概率有限元法对金刚石圆锯片进行可靠性分析，选用Monte-Carlo概率设计方法对?350 mm的金刚石圆锯片进行1000次循环抽样，对金刚石圆锯片的可靠性及灵敏度进行研究。研究结果表明:金刚石圆锯片的不可靠度随着阀值的增大而增加，对金刚石圆锯片的振动灵敏度影响最大的是金刚石圆锯片的厚度。这对于优化金刚石圆锯片的结构，提高金刚石圆锯片的使用寿命和锯切质量有着重要意义。

| Abstract: | Severe vibration frequently happens on diamond circular saw blade during the cutting process.The stochastic finite-element method is applied to analyze diamond circular saw blade,and the Monte-Carlo probability designed method to study the reliability and sensitivity by conducting cycle sampling of ?350 mm diamond circular saw blade for 1000 times.The study states that the unreliability increases with the threshold value rising,and that the vibration sensitivity is greatly affected by the thickness of corresponding diamond circular saw blade.The result will play an essential role in optimizing the structure,prolonging the service life and enhancing saw cutting quality of the diamond circular saw blade. |
