关于客户
LG 电子公司是消费电子、移动通信和家用电器领域的全球领导者和技术创新者。 LG 2012 年全球年销售额为 452.2 亿美元,是业界领先的平板电视、移动设备、空调、洗衣机和冰箱生产商之一。该公司不断开发新版本的智能手机,使其成为电子行业销售最快、发展最快、最具竞争力的产品之一。新车型的上市时间对公司的盈利能力、定位和消费者声誉产生重大影响。
挑战
智能手机行业是电子行业发展最快、竞争最激烈的行业之一。新型号每隔几个月就会开发出来,上市时间的任何缩短都会对制造商的盈利能力、定位和声誉产生重大影响。然而,开发过程的某些方面(例如跌落测试模拟)仍然非常耗时且难以加速。跌落测试模拟是确保智能手机质量和稳健性的关键要素。尽管使用计算机模拟进行虚拟跌落测试,但由于智能手机中存在大量零件和组件、耗时的几何清理、简化和网格划分以及大量接触,LG电子 (LGE) 在缩短模拟时间方面面临着挑战需要许多手动步骤的定义。全面的测试涉及各种跌落和弯曲条件,其中分析设置非常耗时。后处理和生成报告也缩短了取得结果的总时间。平均而言,跌落测试模拟需要一到两周的时间来设置、执行和分析,其中建模和后处理占了投入时间的 60% 到 80%。
解决方案
LGE 与 Altair 合作,旨在创建一个无缝集成的跌落测试模拟自动化系统,使 LGE 工程师能够在短短 24 小时内进行虚拟智能手机跌落测试。这种方法结合了建模以及跌落和弯曲分析,预计将显着加快开发过程,并为 LGE 提供巨大的竞争优势。 Altair-LGE 团队开发了一种方法,可以使用 Altair 的 HyperWorks 计算机辅助工程套件自动简化几何形状、创建焊点、生成高质量网格以及在零件之间创建接触。该套件包括用于预处理的 HyperMesh、RADIOSS 解算器、用于后处理的 HyperView 及其嵌入式自动化框架。 Altair-LGE 团队开发的自动化系统仅需几个小时,是一个完全集成、端到端且用户友好的系统,可以模拟跌落和弯曲测试场景。该系统还提高了跌落和弯曲分析的标准化、可靠性和可重复性。

Improving Vending Machine Profitability with the Internet of Things (IoT)
The vending industry is undergoing a sea change, taking advantage of new technologies to go beyond just delivering snacks to creating a new retail location. Intelligent vending machines can be found in many public locations as well as company facilities, selling different types of goods and services, including even computer accessories, gold bars, tickets, and office supplies. With increasing sophistication, they may also provide time- and location-based data pertaining to sales, inventory, and customer preferences. But at the end of the day, vending machine operators know greater profitability is driven by higher sales and lower operating costs.
