在多物体同时接触轧制工程问题中,对各物体抽象出来研究存在简化较多、计算精度低等缺点。开发了多物体弹塑性摩擦接触多极边界元法,对板带四辊轧制接触问题进行了数值模拟,获得了板带轧制压力和轧机轴承载荷分布规律。并通过对轴承载荷特性的实验,证明了多物体接触快速多级边界元法具有计算精度高、计算速度快等优点,是分析轧制工程中接触问题的最有效的数值工具之一。
In the simultaneous multi-object rolling engineering problems, the abstract of the various objects to study there is more simplification, low accuracy and other shortcomings. A multi-object elasto-plastic friction contact multipole boundary element method was developed to simulate the strip rolling contact problem. The strip rolling pressure and rolling mill load distribution law were obtained. Through the experiment of bearing load characteristics, it is proved that multi-objects contact with fast multistage boundary element method has the advantages of high precision and fast calculation speed. It is one of the most effective numerical tools to analyze the contact problem in rolling engineering.
