摘要
疲劳破坏是机械设备在工作过程中的诸多破坏形式当中最常见的。液压机的主要零部件大多是在承受了多次交变载荷之后而疲劳破坏的。本文利用ANSYS Workbench有限元分析软件,对YT25-1000快速热成型液压机进行设备-模具耦合分析,考虑热成型工艺要求液压机保压时间长的特殊条件,得到热成型液压机的支柱疲劳情况,为液压机机身设计提供理论基础,从而保证液压机的正常使用,降低因疲劳破坏造成的事故发生及经济损失。
Fatigue failure is most common in many forms of destruction when machinery equipments is working. After withstanding multiple alternating loads, fatigue failure is found in most of main components of a hydraulic machine. YT25-1000 rapid hot press hydraulic press was analyzed in the mold of equipment-mold coupling by the finite element analysis software ANSYS Workbench. The long time of pressure keeping that hot press process requires to the hydraulic press was considered. Pillar fatigue analysis of the hydraulic press provides a theoretical basis for the hydraulic press body design, and ensures that the hydraulic press can be used normally to reduce accidents and economic Joss caused by fatigue damage.
