曲轴断裂面的呈现特征表明，曲轴的几何形状、边界条件、作用载荷构成和制造的工艺因素都极其复杂，各项成因都可能成为诱发曲轴断裂的因子。本文仅从疲劳的特征，运用疲劳理论分析疲劳断裂的机理，并以此为脉络分析曲轴断裂的成因，佐证曲轴作用载荷的控制机理。运用证明，通过控制疲劳因素，从而有效的遏制住冲压压力机曲轴断裂这一重大事故的蔓延，明确了冲压压力机负荷选择的机理理论。

The characteristic of fractured surface indicates that the geometrical shape, boundary conditions, constitution of the work load and manufacturing process of the crank are all extremely complicated. Various reasons can lead to the fracture of the crank. This paper analyzes the mechanism of fatigue fracture based on the fatigue theory from its characteristics; and it analyzes the reasons of the crank fracture along with this theory and proves the mechanism of controlling the crank’s work load. The contagion of the serious accident of pressure machine crank facture can be effectively restrained and the theory of choosing work load of pressure machines are clarified.
