挑战
Bremar Automotion 是一家位于澳大利亚墨尔本的工程设计公司,面临着通过全尺寸防滚架物理测试来确认计算机建模准确性的挑战。这是获得澳大利亚汽车运动联合会 (CAMS) 和国际汽车联合会 (FIA) 认证的先决条件。防滚架是任何赛车的一项重要安全功能,旨在在发生事故时保护驾驶员,特别是涉及车辆侧翻的事故。在许多车辆中,防滚架还构成底盘的主要结构,它们通常是刚度、安全性、重量和成本之间的复杂折衷方案。作为认证过程的一部分,Bremar Automotion 需要通过将 FIA 指定的防滚架载荷应用于结构来构建和测试全尺寸防滚架。需要进行破坏性测试来确认其计算机建模的准确性并向国际汽联证明其能力。
关于客户
Bremar Automotion 是一家位于澳大利亚墨尔本的工程设计公司。他们专注于使用计算机辅助工程 (CAE) 来模拟、测试、验证和优化设计,涉及汽车、卡车和拖车、采矿、工业设备和赛车等一系列行业。 Bremar Automotion 最近获得 CAMS 和 FIA 的批准,可以使用有限元分析 (FEA) 对赛车防滚架进行认证。这项享有盛誉的认证仅授予 FIA 技术清单第 35 号中的认可机构,使 Bremar 能够在澳大利亚和国际上使用 FEA 独立认证赛车防滚架。
解决方案
Bremar Automotion 使用 Altair 的 RADIOSS 进行非线性有限元分析。用于物理测试的防滚架由 Bremar 设计,可在施加的载荷下导致结构发生显着的塑性变形。这需要非线性、高位移和塑性变形有限元分析。由于 Bremar 工程师已经是 Altair HyperWorks 产品的经验丰富的用户,因此 RADIOSS 是满足该项目非线性分析要求的最佳选择。他们首先设计了一个适合测试台的低碳钢防滚架,该测试台松散地围绕着一辆重约 1200 公斤的中型车辆。主防滚环所需的 FIA 负载约为 10T。一旦满足 FIA 负载标准,他们还对主环进行了另一项测试,其中应用了 50 毫米的最大允许位移,这需要远超过 20T 的负载。防滚架配备了多个传感器和应变仪,以测量结构上不同位置的挠度和应变,并与有限元分析模型建立关联。

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).

Underground Mining Safety
The goal was to produce a safety system to monitor and support underground mining operations; existing systems were either too simple (i.e. phone line) or overly complex and expensive, inhibiting deployment, and providing little-to-no support in event of an accident. Given the dangerous nature of the mining work environment and the strict regulations placed on the industry, the solution would have to comply with Mine Safety and Health Administration (MSHA) regulations. Yet the product needed to allow for simple deployment to truly be a groundbreaking solution - increasing miner safety and changing daily operations for the better.

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.
