关于客户
保时捷公司是一家全球知名的汽车公司，以其高性能汽车而闻名。为了应对电动汽车的挑战，保时捷正在开发高性能电动动力总成，在性能、燃油效率、驾驶动力和日常实用性方面满足保时捷的所有标准。该公司致力于改善电机开发的总体设计平衡，并热衷于采用更加集成和整体的开发策略，以更好地满足未来的需求，而不会在目标实现上做出重大牺牲。保时捷致力于创新，始终寻找增强其产品和服务的方法，为客户提供最佳体验。
挑战
保时捷公司是一家著名的汽车公司，面临着改善电机开发总体设计平衡的挑战。电动汽车动力系统的开发必须考虑到越来越多的内部、客户和法律要求。经典的开发策略涉及针对不同需求的单独开发路线以及负责满足这些需求的不同组织结构。这导致开发在多个平行学科中进行，通常会导致谈判和不利的妥协，以达到最终可接受的设计。保时捷旨在采取更加综合和全面的发展战略，以更好地满足未来的需求，同时又不会在目标实现上做出重大牺牲。面临的挑战是设计优化策略，同时考虑不同物理现象产生的不同要求，即多物理场优化。
解决方案
Porsche AG 与 Altair（一家专门从事仿真、优化和高性能计算的软件和咨询公司）合作，应对改善电机开发总体设计平衡的挑战。 Altair 的工具套件（包括 Altair Flux、Altair FluxMotor、Altair OptiStruct 和 Altair Activate）用于创建多物理场电机优化流程。经典的电机效率/功率设计问题与其他物理问题相结合，以考虑热效应、结构边界条件和振动。还通过集成控制和物理建模来评估逆变器对电机性能的影响。设计优化的目的是在规定的驱动条件下最大限度地提高扭矩和功率，同时将转子应力、电机振动和电机温度保持在一定范围内。设计过程考虑了单个电机设计点，并使用基于 Altair 工具套件中全阶模型提供的数据的降阶模型对标准化驾驶周期进行评估。

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).

Hydro One Leads the Way In Smart Meter Development
In 2010, Ontario’s energy board mandated that time-of-use (TOU) pricing for consumers be available for all consumers on a regulated price plan. To meet this requirement, Hydro One needed to quickly deploy a smart meter and intelligent communications network solution to meet the provincial government’s requirement at a low cost. The network needed to cover Hydro One’s expansive service territory, which has a land mass twice the size of Texas, and its customers live in a mix of urban, rural, and remote areas, some places only accessible by air, rail, boat or snowmobile. Most importantly, the network needed to enable future enterprise-wide business efficiencies, modernization of distribution infrastructure and enhanced customer service. To meet these needs, Hydro One conceptualized an end-to-end solution leveraging open standards and Internet Protocols (IP) at all communication levels. The utility drew upon industry leaders like Trilliant to realize this vision.

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.
