摘要
针对轨梁厂粗轧机齿轮座下箱体底座圆弧处产生裂纹的问题,为挖掘其与"咬钢"冲击之间的关系,先建立该轧机主传动系统的CAD模型,并导入ANSYS Workbench,利用其LS-DYNA模块完成了对BD1轧机轧制过程的数值模拟,分析了不同的"咬钢"速度对应的粗轧机齿轮箱应力及形变量,并判断其出现异常的原因,为设置合理的"咬钢"速度提供理论依据。
the problem of cracks in rail mill gear box under the seat base arc, for the mining and relationship between the impact of biting ', CAD model was established on the main drive system of the rolling mill, and imported into ANSYS Workbench, using the LS-DYNA module to complete the numerical simulation of the BD1 rolling process. Analysis of the different' biting 'speed corresponding to the rolling mill gear box stress and deformation, and determine the causes of the abnormal, to set reasonable' biting 'provides a theoretical basis for speed.
