关于客户
东南汽车是一家中国汽车制造商,其使命是“提供令人兴奋的移动生活方式,培育有文化的汽车社区”。经过二十多年的经营,东南集团成功整合了克莱斯勒、三菱等国际知名企业的先进技术,在中国建立了东南、三菱两大品牌。展望未来,东南在继续与国际企业合作的同时,致力于强化自身研发能力和产品品牌。 DX7是东南汽车基于3.0战略进军竞争激烈的SUV市场的新产品。 DX7的外观和内饰由拥有100多年欧洲领先概念汽车设计经验的意大利顶级设计公司Pininfarina设计,并采用三菱技术的世界质量和安全标准体系。
挑战
中国汽车制造商东南汽车面临着优化 DX7 车辆碰撞性能同时减少对物理测试的依赖的挑战。碰撞安全是研发过程中至关重要的一环,设计具有良好碰撞能量吸收性能的车身是汽车设计的主要目标之一。然而,由于原型碰撞测试的成本很高,仅通过反复试验来验证设计的可行性是不切实际的。虚拟仿真成功与否的关键取决于仿真结果是否准确反映了物理测试结果。 DX7 项目的目标是在时间和预算紧张的情况下实现最佳的耐撞性。两个主要挑战是确保 CAE 仿真结果准确反映物理碰撞测试以及分析和优化约束系统。
解决方案
为了克服这些挑战,Soueast 与 Altair 的工程服务部门 Altair ProductDesign 合作。该团队利用 HyperWorks 套件及其 RADIOSS 求解器来模拟和优化 DX7 车辆的碰撞性能。此过程包括分析当前的结构和约束系统,并提出可以提高性能的潜在改进设计建议。 DX7 车身结构开发中的一个关键载荷工况是 C-NCAP 高速 40% 偏移可变形屏障。然后使用 HyperStudy 对保险杠梁、纵梁、猎枪式、强制降档和门槛设计进行了广泛的优化。最终达到了加速和侵入效果的目标,并且还减轻了前车体的重量。在约束系统的开发方面,对转向柱挤压、脚踏板设计、座椅设计、安全带限力器、安全气囊尺寸和通风口进行了优化。

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).

IoT Data Analytics Case Study - Packaging Films Manufacturer
The company manufactures packaging films on made to order or configure to order basis. Every order has a different set of requirements from the product characteristics perspective and hence requires machine’s settings to be adjusted accordingly. If the film quality does not meet the required standards, the degraded quality impacts customer delivery causes customer dissatisfaction and results in lower margins. The biggest challenge was to identify the real root cause and devise a remedy for that.
