大型挤压机因其结构复杂,很难利用传统方法对其受力情况进行详细分析,容易产生安全隐患。采用workbench对大型挤压机的主要受力部件--箱梁进行静力学数值模拟分析,首先对大型板材的受力进行理论计算和数值模拟,以此确定合适的网格类型及网格尺寸等关键模拟参数。接着以这些参数为基础,加入材料和结构的非线性因素,对箱梁进行数值模拟,计算出在3500吨压力下箱梁各部分的位移及应力分布情况,最后根据计算结果对箱梁的结构提出改进方案。数值模拟对大型挤压机的设计具有一定的指导意义。
Due to its complex structure, the large-scale extrusion machine is difficult to use the traditional method to conduct detailed analysis on its stress situation and easily cause potential safety problems. Using workbench, the main force component of large extrusion machine - box beam static and dynamic numerical simulation analysis, first of all, the theoretical calculation of large plates and numerical simulation of stress in order to determine the appropriate grid type and grid size Key simulation parameters. Then based on these parameters, the nonlinear factors of material and structure are added to simulate the box girder. The displacement and stress distribution of each section of the box girder under 3,500 tons of pressure are calculated. Finally, the structure of the box girder Propose improvement plan Numerical simulation of large-scale extrusion machine design has a certain significance.
