摘　　要：对 8 5 0mm× 2 5 0mm扁挤压筒 ,采用双层预应力结构模型 ,模型尺寸按实际尺寸的 1/10设计 ,用有限元方法进行受力分析 ,并进行了模拟试验 ,得到的结果与实际情况基本一致 ,为进一步对扁挤压筒结构的优化设计提供了依据。In view of 850mm×250mm flat extruded cylinder, double prestressing force structure model is designed. The size of the model is designed based on 1/10 of the practical size. By finite element method, the stress is analyzed and the experiment of the model is simulated. The result is basically in accordance with the practical condition, which provides bases for the optimum designing of the structure of the flat extruded cylinder.
