摘要
根据连铸机拉矫辊实际工况,利用ANSYS有限元软件对连铸机拉矫辊建立三维热分析模型,得到了拉矫辊的温度场分布规律,并在温度场分析的基础上,通过转换分析单元及外应力载荷的加载,实现热应力和外载荷的耦合分析,得到拉矫辊的应力场分布规律;并在温度应力场分析的基础上进行了拉矫辊失效分析。
According to the actual working condition of straightening roller of CCM, ANSYS Finite Element Analysis Software is used to establish the three - dimension model of the pulling - straightening roller. Thanks to ANSYS thermal analysis, the distribution of thermal field is obtained. Based on the analysis, the coupled analysis of the thermal stress and external load is implemented by means of switching analytic element and loading external stress. And the rule of roller＇s stress field gains hence..Finally, there is a failure analysis of pulling - straightening roller on the basis of its thermal field and stress field in the paper.
