摘　　要：针对楔横轧机工作机座和辊系结构复杂特点,开发了楔横轧机整体刚度的三维弹性多物体接触边界元有限元耦合新算法,更新已有材料力学、弹性力学及有限元法计算刚度的变形分离计算理论以及传统计算轧机刚度不包括辊系的做法,具有综合性强,接触型计算模型假设少,计算速度快和计算精度高等优点。As to the complexity in structure and shape of work house and roll system in cross wedge mills, the new method is developed to calculate the rigidity of cross wedge mill, which is called the coupling method of 3-D elastic contact boundary element method with multi-bodies and finite element method. The new method can update the existing deforming separation calculating theory and corresponding methods of material mechanics, elastic mechanics and finite element method. It gets over the disadvantage of not inclusion of roll system in the traditional calculation of rigidity. It has stronger synthesis and fewer hypotheses in contact-type calculating model. This new method owns high calculation rate, high calculation accuracy, etc.
