摘要：压铸机头板是压铸机核心部件之一，为研究其结构的优劣对压铸机使用寿命的影响，首先建立三维实体模型；然后在定义设计疲劳曲线（SN曲线）的基础上，利用Solidworks Simulation软件对压铸机头板进行疲劳分析，从中得出头板的对等应力以及生命周期等相关数据，得知头板凸台处为薄弱区；最后对其结构优化改进，重新进行有限元分析，提高了头板的生命周期。研究结果表明，该研究为预测压铸机的疲劳寿命提供了理论依据。

Abstract: Head board is one of the core components of die casting machine, for the numerical study of the structure affecting service life of die casting machine, first, the threedimensional entity model was established. On the basis of the definition of the design fatigue curves(SN curves), the fatigue property of die head plate using Solidworks Simulation software was analysed, and the equivalent stress and the life cycle and other relevant data of the head board were obtained . From this it can be learned that the vulnerable spot of die head plate is the flange. Finally, optimized to improve its structure and reconducted the FEA to improve the life cycle of the first board. The research results show that the analysis can predict the fatigue life of die casting machine to provide a theoretical basis.
