挑战
维克森林浸信会医学中心是生物医学科学和生物工程领域领先的研究型大学,其任务是开发用于车辆碰撞模拟的高度详细的有限元人体模型。该大学的伤害生物力学中心 (CIB) 旨在研究车祸造成的创伤后的伤害机制,以更好地了解人类对伤害的耐受性,并设计增强的安全对策。挑战在于以数学方式量化易受创伤的人体基本器官、骨骼成员和身体四肢。由此产生的医学图像数据必须准确代表一系列车辆乘员:成人(男性和女性)、儿童(3-6 岁)和婴儿。然后必须对人体数据进行离散化,以生成各种人体系统的精确有限元 (FE) 模型。然后必须整合这些模型以制定整个人体的模型,然后必须在车辆耐撞性模拟中对乘员和行人的碰撞条件进行验证。
关于客户
维克森林浸信会医学中心是一所生物医学科学和生物工程领域领先的研究型大学。维克森林浸信会医学院损伤生物力学中心 (CIB) 研究车祸造成的创伤后的损伤机制,以更好地了解人类对损伤的耐受性,并设计增强的安全对策。自 2006 年以来,博士。 CIB 的 Joel Stitzel 和 Scott Gayzik 一直是全球人体建模联盟 (GHBMC) 的主要研究员,该联盟是一个由汽车制造商和供应商组成的国际联盟,与研究型大学和政府机构合作,推进碰撞模拟的人体建模技术。
解决方案
全球人体建模联盟 (GHBMC) 应用 Altair HyperMesh 及其 HyperMorph 模块,根据人体器官、组织和骨骼系统的大量扫描数据开发详细的有限元模型。该数据是在选定大学已建立的 GHBMC 专业中心 (COE) 的指导下开发的。每个中心都负责人体特定区域的 CAD 和有限元建模。建立了一个额外的 COE,将每个子系统的数据和有限元模型集成到全身模型中。 GHBMC 选择维克森林大学 CIB 来完成人体总体 COE 所需的广泛整合工作。 Altair 提供了整个 HyperWorks CAE 工具套件,以支持每个 COE 的有限元和耐撞性分析相关工作。 HyperMesh用于人体CAD数据的有限元建模,而RADIOSS用于车辆碰撞仿真验证。 Wake Forest Baptist 团队还开发了一种建模缩放方法,利用 M50 开发的大量现有数据(包括外部人体测量和医学成像数据)来快速开发其他尺寸的模型。

Honeywell - Tata Chemicals Improves Data Accessibility with OneWireless
Tata was facing data accessibility challenges in the cement plant control room tapping signals from remote process control areas and other distant locations, including the gas scrubber. Tata needed a wireless solution to extend its control network securely to remote locations that would also provide seamless communication with existing control applications.

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).

Advanced Elastomer Systems Upgrades Production
In order to maintain its share of the international market for thermoplastic elastomers AES recently expanded its Florida plant by adding a new production line. While the existing lines were operating satisfactorily using a PROVOX distributed control system with traditional analog I/O, AES wanted advanced technology on the new line for greater economy, efficiency, and reliability. AES officials were anxious to get this line into production to meet incoming orders, but two hurricanes slowed construction.
