关于客户
德纳控股公司是传动系统、密封和热管理技术领域的全球领导者,这些技术可提高乘用车、商用车和非公路车辆的燃油效率、减少排放并降低拥有成本。德纳拥有 25,000 名员工,业务遍及 27 个国家,拥有约 90 个工程、制造和分销设施网络。动力总成部件的计算机仿真,涉及创建具有 25,000 个或更多表面的超大型模型,一直是德纳产品开发流程的一个重要方面。
挑战
德纳控股公司是传动系统、密封和热管理技术领域的全球领导者,在产品开发过程中面临着重大挑战。将 CAD 设计转化为原型、分析原型的故障点、重新设计原型并重新测试直至产品符合规格的传统方法被证明既耗时又昂贵。特别是,气缸盖和发动机缸体模型的预处理需要从 CAD 导入几何形状,然后由工程师进行清理,这项任务可能需要一到四天的时间。为了加快设计周期,Dana 决定实施“一次成功”的设计方法,即在构建原型之前进行分析。这个新过程需要一种更快的方法来预处理仿真模型。
解决方案
Dana 采用 Altair 的 SimLab 来解决他们的挑战,该工具可以自动执行许多预处理步骤。 SimLab 从 CAD 系统导入原生几何体,进行网格划分,创建曲面和节点集,并创建接触对,所有这些都只需最少的用户干预。 Altair 与 Dana 密切合作,将 SimLab 集成到其流程中,展示 SimLab 如何缩短 Dana 的建模时间,并为 Dana 提供试用 SimLab 功能的培训。 Altair 还帮助 Dana 创建模板,这是一组已定义的设置,Dana 工程师可以将其用于所有发动机模型和其他组件。这确保了每个使用这些模板进行网格划分的工程师都会获得具有相同属性的相似网格。 Dana 发现 SimLab 用户友好、高度灵活,并提供有价值的后处理功能。

Case Study
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).

Monitoring of Pressure Pumps in Automotive Industry
A large German/American producer of auto parts uses high-pressure pumps to deburr machined parts as a part of its production and quality check process. They decided to monitor these pumps to make sure they work properly and that they can see any indications leading to a potential failure before it affects their process.
