本文用组合结构接触应力分析的有限单元法分析了圆头楔形刀具作用下岩石内的应力场,得出了盘形滚刀对岩石的破碎作用主要是突进破碎,而突进破碎是受拉破坏。大量实验证实这个结论是正确的。
In this paper, the finite element method of combined structure contact stress analysis is used to analyze the stress field in the rock under the action of a circular wedge-shaped cutter. It is concluded that the crushing effect of the disk-shaped hob on the rock is mainly sudden crushing, while the crushing of the crusher is tensile damage. A large number of experiments confirmed that this conclusion is correct.
