摘要
以高温冶金熔渣粒化装置支撑柱为研究对象,利用SolidWorks对支撑柱进行了三维建模,然后将模型文件导入ANSYS Workbench开展强度有限元计算。首先对支撑柱进行了有预应力的模态分析,得出了支撑柱的固有频率和振型,对比模态分析结果和粒化装置的实际工况,发现支撑柱的最小固有频率远离粒化装置的不平衡激振频率,表明该支撑柱结构不会在粒化装置的不平衡激励下发生共振。此外,对支撑柱在承受冲击载荷工况下的强度进行了分析,研究结果表明,冲击载荷下两层平台的支撑面上应力最大,但不超过材料屈服极限,为保证运行安全,可以在两层平台的支撑面处焊接筋板提高支撑强度。
Taking the support column of high temperature metallurgical slag granulation device as the research object,3D model of the support column was established using SolidWorks,and then the model file was imported into ANSYS Workbench to carry out the strength finite element calculation.Firstly,the pre-stressed modal analysis of the support column was carried out,and the natural frequency and vibration mode of the support column were obtained.By comparing the modal analysis results with the actual working conditions of the granulation device,it is found that the minimum natural frequency of the support column is far away from the unbalanced excitation frequency of the granulation device,which indicates that the support column structure will not resonate under the unbalanced excitation of the granulation device.In addition,the strength of the support column under the impact load condition was analyzed.The research results show that the stress on the support surface of the two-story platform under the impact load is the largest,but does not exceed the yield limit of the material.In order to ensure the safety of operation,the rib plate can be welded on the support surface of the two-story platform to improve the support strength.
