关于客户
联想是一家中国跨国科技公司，总部位于中国北京和美国北卡罗来纳州。联想成立于1984年，至今已有30年历史，2013年成为全球第一大个人电脑制造商。联想生产多种产品，包括个人电脑、平板电脑、智能手机、工作站、服务器、电子存储设备和智能电视。该公司在 60 多个国家开展业务，产品销往 160 多个国家。联想在北京创新设计中心拥有专门的CAE技术平台，支持其所有产品系列的开发。
挑战
联想作为一家领先的跨国科技公司，面临着计算机行业的激烈竞争，需要不断降低成本，提高产品质量和可靠性，缩短产品开发周期。传统的产品开发方法已不再能够有效地加快上市速度。联想试图在初始产品设计阶段使用计算机辅助工程（CAE）工具来优化性能，以模拟和评估其产品在冲击和振动等负载下的机械行为。然而，工程师将 80% 的时间花费在仿真过程中的预处理任务上。一些CAE软件提供的预处理工具不够强大，无法满足制造商的要求，并且预处理网格的质量也不可靠。联想需要一个强大的预处理工具来满足科学研究和工程创新的需求。
解决方案
联想选择了 Altair HyperWorks 套件的重要组件 HyperMesh，以提高效率、提高网格划分质量并缩短 CAE 仿真时间。 HyperMesh 是一种高性能有限元预处理器，可提供高度交互和可视化的环境来分析产品设计性能。它提供了联想所追求的速度到质量结果，从而实现了非常快的开发周期。联想还扩大了 HyperWorks 套件的使用范围，将 OptiStruct 应用于硬盘驱动器的设计。 OptiStruct 用于优化系统，克服了试错法固有的许多缺陷。联想的工程师使用 OptiStruct 进行模态分析，以优化计算机系统的固定侧，避免与旋转硬盘的 120 Hz 固有频率发生共振。联想还利用用户友好的 HyperMesh 界面以及 CFD 软件和强大的几何处理功能来快速生成高质量的 CFD 元素。

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.
