关于客户
Trèves Products Services & Innovation 是一家总部位于法国的公司,2021 年营业额为 5.8 亿欧元。作为领先的降低噪声、振动和声振粗糙度 (NVH) 零件的一级供应商之一,Trèves 为行李箱、车身、内饰和动力总成。该公司拥有 4,900 名员工,其中 300 名研发工程师分布在 9 个技术中心,在 17 个国家设有 26 家工厂。他们致力于满足超过 15 个 OEM 客户的要求。 Trèves 在多孔弹性声音包的表征和建模方面拥有众多专家,并且已成功使用 AlphaCell 超过 5 年。
挑战
Trèves Products Services & Innovation 是一家领先的降低噪声、振动和声振粗糙度 (NVH) 零件的一级供应商,在缩短零件设计和交货时间方面面临着挑战。传统方法需要对真实零件进行昂贵且耗时的物理测试,以考虑其多层排列和变化的厚度。这些模型的输入参数也需要随时可用。此外,模型必须范围全面且易于实施。预计到 2024 年,路过噪声排放限制将从 70 分贝降低至 68 分贝,因此准确预测噪声水平的能力变得至关重要。面临的挑战是用数值建模代替物理测试,以满足客户期望和监管要求。
解决方案
Trèves 求助于 Matelys 研究实验室的 AlphaCell(可通过 Altair 合作伙伴联盟 (APA) 获取)来解决他们的挑战。 AlphaCell 提供了满足 Trèves 需求的多项功能,包括能够在几秒钟内预测扩散声场条件下多层配置的响应,例如在阿尔法舱测试中遇到的情况。通过根据初始材料属性预测的任何压缩零件,可以快速、用户友好的方式考虑不同厚度的影响。该模型的声学输入参数是通过 Trèves 使用 Matelys 软件套件和设备掌握的专用表征过程确定的。使用模型直观的拖放界面,可以轻松地将仿真结果与测量数据进行比较。在该项目中,将多种厚度生产的扁平样品的数据与真实的发动机罩部件进行了比较。

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.
