摘要：

针对目前H型钢多道次热轧工艺中轧件内部变形信息不透明问题，以ABAQUS求解器为基础构建了一个综合仿真系统。该系统可模拟分析各道次轧制过程中轧件内部应力、应变和温度场分布情况，同时较好地解决了以往仿真系统中前处理操作繁琐、道次间网格重构困难以及后处理信息提取不便等问题，实现了分析流程的自动化。以H400×200型钢的粗轧第一道次和一、二道次间隙的分析为例，验证了系统的可靠性。

In view of present problem that interior information of H\|beam in multi-pass hot rolling process is not clear enough, an integrated simulation system was built based on solver of ABAQUS. The system could be used to simulate and analyze distribution of stress, strain, and temperature for workpiece in every pass of hot rolling, furthermore, problems to previous simulation systems that include complicated jobs in pre-processing, difficulties in re-meshing of inter-pass, and inconvenient information extraction in post-processing could be solved effectively with the system, which makes the analysis procedures to be automatic. Take the analysis in the first pass and the inter-pass between the first and the second of H400×200 for example, the system is verified reliably.
