关于客户
Scania CV AB 是一家总部位于瑞典的全球领先的重型卡车、公共汽车和其他重型发动机应用制造商。该公司以产品高度定制化能力而闻名,提供大量发动机型号、传动系统和底盘供客户选择。这使得客户能够极大地个性化他们的卡车。 2006年,斯堪尼亚在欧洲、拉丁美洲、亚洲、非洲和澳大利亚共销售了65,000辆汽车。
挑战
斯堪尼亚是全球领先的重型卡车、公共汽车和其他重型发动机应用制造商,以其高度定制产品的能力而闻名。然而,这种定制过程给斯堪尼亚的计算机辅助工程 (CAE) 部门带来了重大挑战。工程师必须通过有限元 (FE) 模拟快速验证大量不同的变体。自动化整个虚拟模型装配过程是斯堪尼亚的主要目标。该过程包括定位数百个组件、创建接触定义以及使用预紧螺栓构建零件连接等任务,非常耗时且容易出错。过去,斯堪尼亚分析师使用全自动解决方案,在执行过程中无法进行用户交互。由于缺乏自动化交互性,斯堪尼亚 CAE 分析师通常需要手动修改和改进卡车输入模型,从而进一步增加了耗时的过程。
解决方案
为了构建一个允许用户交互的自动化流程,Scania 选择了 HyperWorks CAE 框架。该框架提供了多种技术优势,包括本地计算机辅助设计 (CAD) 支持、用于高级实体几何的网格划分工具、可轻松转换为各种格式的全面解算器中立数据模型、通过 HyperWorks 流程自动化引擎实现的自动化功能以及在提交作业之前以交互方式管理组装的有限元模型。基于HyperWorks框架,针对底盘部门的特殊建模需求,开发了半自动预处理管理器。该应用程序执行的任务包括读取 CAD 库并自动选择适当的文件、监控 FE 和几何库、将组件定位到底盘中的正确位置、在几何形状/网格中切孔以准备螺栓连接以及生成“星形连接”、 ” 具有预紧力和接触定义的实心螺栓。

Transformation for IoT Business Model in Connected Industrial Vehicles
CNH Industrial wanted to put IoT-enabled viechles onto the market. Whether monitoring a single machine or integrating an entire fleet, operators are able to track the status, speed, and movement of machines and their performance and also receive alerts on issues that may require service by a qualified technician to improve uptime and overall effectiveness of the vehicle.
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).
