关于客户
伊顿航空航天集团是为世界上许多军用和商用飞机提供液压元件和系统的领先供应商。位于密西西比州杰克逊的液压系统部门特别专注于液压泵、执行器、电机和相关组件的设计和测试。该部门进行了一系列测试，包括应力分析、计算流体动力学和动态模拟，以确保组件按预期工作。该部门特别专注于疲劳分析和压力分析。该部门的分析小组处于产品开发过程的最前沿，分析各种飞机的零件或组件，以确定组件是否满足负载要求。
挑战
位于密西西比州杰克逊的伊顿航空航天集团液压系统部门负责为世界上许多军用和商用飞机设计液压部件和系统。该部门对其许多设计进行虚拟测试，包括应力分析、计算流体动力学以及液压泵、执行器、电机和相关组件的动态仿真。然而，该部门在提高网格划分效率方面面临着重大挑战。 2002 年之前，分析小组使用求解器中内置的流程来处理有限元模型。该过程不是为有限元分析而设计的，并且通常无法提供处理复杂液压部件时所需的质量网格。对复杂的液压元件几何形状进行网格划分需要大量的精力和时间，使得该过程效率低下且繁琐。
解决方案
为了应对这一挑战，伊顿团队求助于 HyperMesh，它是 Altair Engineering 的 HyperWorks 套件的一部分。 HyperMesh 是由伊顿高级压力分析师 Ahmad Sereshteh 引入团队的，他在伊顿汽车部门使用该工具已有 20 年。 HyperMesh 用于分析复杂的内部流体通道，确定它们相交的正确角度以及中心线的适当位置。该工具使用具有相当复杂几何形状的发动机驱动泵 (EDP) 缸体进行了演示。在之前的过程中，为该组件创建有限元模型具有挑战性，需要三到四天才能完成。然而，使用 HyperMesh，该过程在速度、准确性和置信度方面得到了显着提高。

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.
