巨型水压机主工作缸的有限元分析

Static analysis of the fluid cylinder of giant hydraulic press bed with finite element method

应用有限元分析软件MSC.MARC对巨型水压机的主工作缸进行静力分析。以三万吨水压机的主工作缸为研究对象,模拟其在最大工作压力(45MPa)下的应力分布,并与实际测量值对比,验证了有限元模型及分析的准确性。同时分析了在仅改变螺钉位置的情况下,主工作缸各主要应力集中处的应力变化规律。

The author apply the MSC.MARC finite element analysis software to analysis the static stress distribution of the fluid cylinder of giaut hydraulic press bed. Take primary working cylinder of the 300MN hydraulic press bed as subject investigated, and analyze stress distribution when it worked under the maximum working pressure-45MPa. Then we justify it by comparing with the measured value. At the same time, the author discovered the regularity of variation of stresses at each stress concentration point as the mechanical bolt changed its position.
