以此为基础，并借助于上限原理和最小能量原理，获得了楔横轧成形阶梯轴时轧件表面缺陷形成的必要条件。
The frozen coal destruction is the tension stress destroys , and establish the frozen coal cutting model in this foundation , obtains the cutting force , feeding force , tooth spacing according to the smallest energy principle . bring forward a rotary drilling mothod to unload the frozen coal , the broken ability is strong , without frozen depth limits , then obtains this machine working parameters , has combined this method with a grab and determined the plane of vehicle - carried rotary drilling movable coal - unloader
冻煤破坏是拉应力破坏,在此基础上建立了冻煤的切削模型,根据最小能量原理得到截割力,进给力和截齿间距的计算公式,分析得到截割力与切削厚度成正比,随着前角的增大而减小;截齿最优截距与截齿尺寸有关且与切屑厚度成正比;进给力随着截齿前角增大而增大的规律。
