根据锥形筒体的结构特点,分析了坯料外形结构与实际预制坯料的形状,使用有限元分析软件MARC模拟了锥形筒体成形过程,分析了其金属流动的规律。在实际锻造中使用阶梯状外形结构坯料成功锻造出了超大型锥形筒体。
根據錐形筒體的結構特點,分析瞭坯料外形結構與實際預製坯料的形狀,使用有限元分析軟件MARC模擬瞭錐形筒體成形過程,分析瞭其金屬流動的規律。在實際鍛造中使用階梯狀外形結構坯料成功鍛造齣瞭超大型錐形筒體。

According to the structural characteristics of a cone-shaped cylinder, analysis is carried out on the external structure and the shape of blank. In order to analyze the metal flow behaviors, the finite element analysis software MARC is used to simulate the forging process of a coneshaped cylinder. As a result, the ultra-large cone-shaped cylinder is made successfully by selecting the ladder blank.
