挑战
海尔集团作为全球家电和消费电子产品的领导者,其空调面临着重大挑战。尽管以优质产品而闻名,但空调在运输过程中经常损坏,导致成本增加和交货延误。该公司试图通过进行物理跌落测试来增强其空调和包装的结构,使其更能抵抗跌落损坏。然而,这些测试大大增加了研发成本并消耗了大量时间。此外,由于产品与地面的碰撞是瞬时事件,工程师无法轻松观察损坏过程。他们只能看到结果,但看不到发生的几分之一秒内的应变和形状变化。因此,海尔考虑使用过多的包装材料,但包装的整体设计强度不足。
关于客户
海尔集团是全球最大的家用电器和消费电子产品制造商之一。该公司是其总部所在地中国的行业领导者。海尔的产品销往全球 100 多个国家,因此精心设计的产品包装对于公司能否将产品无损地运送到最远的目的地至关重要。尽管该公司以其优质产品而闻名,但其生产的空调在运输过程中遭到损坏,导致成本上升并导致最终产品交付延迟。
解决方案
为了克服这一挑战,海尔工程师利用 Altair 的 HyperWorks 工具创建跌落测试的虚拟模拟,提供有关所涉及的应力和应变的大量数据。使用 HyperMesh 进行预处理和 RADIOSS 求解器的虚拟跌落测试是针对两种不同类型的空调开发的,以获得更好的见解。对于第一个测试的产品,海尔工程师最初进行了大量的物理测试,以收集有关包装所用材料(例如蜂窝板和 EPS 块)性能的数据。然后用虚拟模型模拟材料测试来校准数据。他们通过产品在轴向压缩下的弹性变形、屈曲、塑性塌陷和脆性断裂来测试蜂窝纸。从物理模型获得应变-应力曲线后,团队模拟了蜂窝纸并虚拟地再现了轴向压缩。虚拟压缩测试曲线与实验物理测试曲线表现出非常好的一致性。对于第二种空调,海尔工程师再次为空调和包装准备了单独的模型,然后使用RADIOSS模拟从包装一角0.8米处跌落,起始速度为3.96毫米/毫秒。

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.
