关于客户
Borçelik 是土耳其领先的镀锌钢生产商,成立于 20 世纪 90 年代初。该公司是 Borusan Holding 和安赛乐米塔尔(世界领先的综合钢铁和采矿公司之一)的合作伙伴。 Borçelik 从事热浸镀锌钢、冷轧钢和热轧(酸洗和涂油)钢组的制造,所有这些钢组都是工业原材料投入。该公司提供广泛的产品,满足家用电器、汽车(OEM 和 Tier 1/2)、板式散热器、建筑、彩色涂层、管道和型材、包装、金属制品和钢铁服务中心等行业的制造商需求。 Borçelik 的 Borçelik 品牌总产能为 150 万吨,Kerim Çelik 品牌的金属加工能力为 50 万吨。
挑战
Borçelik 是土耳其领先的镀锌钢生产商,面临着减少汽车行业排放和燃料消耗的挑战。这需要开发先进的材料和生产工艺。车辆的燃油效率很大程度上取决于车身结构的成功设计以及减轻车身重量的技术的开发。然而,在减轻车辆结构重量的同时,维护乘客安全至关重要。本研究的主要重点是研究构成车身结构的高强度镀锌扁钢的延性断裂行为。
解决方案
Borçelik 利用 Altair® Radioss™ 对设计进行深入的模拟和疲劳分析。该软件利用机器学习和优化技术。通过该结构分析软件,用户可以预测零件在各种载荷下的行为。从实验测试中获得的数据可以应用于使用不同的断裂模型进行数值计算,这些模型将应力三轴性、洛德角或材料断裂的等效塑性应变等变量相关联。 /FAIL/BIQUAD 失效模型特别有用,因为它提供了快速且准确的结果。用户可以仅使用拉伸测试结果,利用材料库中的数据创建材料的断裂轨迹。 Hosford-Coulomb 延性材料断裂可以使用 /FAIL/EMC 失效准则进行建模,该准则支持 3D 元素,特别是对于详细的断裂建模。业界广泛使用的 Johnson-Cook 断裂准则可用于使用 /FAIL/JOHNSON 失效卡进行数值计算。 /FAIL/FLD 失效模型可用于定义成形极限图 (FLD),它表示材料的成形性,特别是在钣金成形分析中。

Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
