关于客户
本案例研究中的客户是一家从事汽车、重型设备和航空航天行业的公司。他们参与车辆的开发,需要验证车辆要求、开发设计参数并向管理层提供实时项目状态。他们有需要满足的燃油经济性以及车身弯曲和扭转模式固有频率的具体目标。他们还使用粗几何模型进行动态有限元分析,并与 CAE 团队密切合作以实现他们的目标。
挑战
汽车、重型设备和航空航天行业在验证车辆要求、开发设计参数以及向管理层提供实时项目状态方面面临着重大挑战。在 Word 文档中捕获需求的传统方法既耗时又低效。此外,使用企业燃油经济性预测软件和电池方程验证这些要求的过程很复杂,并且需要高水平的专业知识。此外,设置车身弯曲和扭转模式固有频率目标以满足计划目标是一项需要精度和准确性的关键任务。该挑战还涉及使用粗略几何模型进行动态有限元分析,这需要将需求和工作请求传输给 CAE 团队。完成后,需要返回结果并自动更新状态,这个过程可能容易出现延迟和不准确。
解决方案
XLDyn 的 MBSE 模型具有集成验证方法,为这些挑战提供了解决方案。最初在 Word 文档中捕获的需求可以在几分钟内导入 XLDyn 并转换为 SysML 图。这不仅节省了时间,还提高了流程的准确性和效率。然后使用企业燃油经济性预测软件和电池方程验证这些要求,确保车辆满足 26 MPG 的城市/公路综合燃油经济性目标。此外,还设置了车身弯曲和扭转模式固有频率目标来满足计划目标。粗几何模型用于动态有限元分析,并将需求和工作请求传输给 CAE 团队。完成后,返回结果并自动更新状态,提供项目状态的实时更新。这使得总工程师能够查看车辆程序的整体状态。

Case Study
Airbus Soars with Wearable Technology
Building an Airbus aircraft involves complex manufacturing processes consisting of thousands of moving parts. Speed and accuracy are critical to business and competitive advantage. Improvements in both would have high impact on Airbus’ bottom line. Airbus wanted to help operators reduce the complexity of assembling cabin seats and decrease the time required to complete this task.
Case Study
Aircraft Predictive Maintenance and Workflow Optimization
First, aircraft manufacturer have trouble monitoring the health of aircraft systems with health prognostics and deliver predictive maintenance insights. Second, aircraft manufacturer wants a solution that can provide an in-context advisory and align job assignments to match technician experience and expertise.
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).

Aerospace & Defense Case Study Airbus
For the development of its new wide-body aircraft, Airbus needed to ensure quality and consistency across all internal and external stakeholders. Airbus had many challenges including a very aggressive development schedule and the need to ramp up production quickly to satisfy their delivery commitments. The lack of communication extended design time and introduced errors that drove up costs.
