Cell phone drop test

跌落测试是产品质量检验重要环节，通过模拟产品在使用过程中可能存在从手中、口袋中跌落在地面上的过程测试，为检验产品抗意外冲击能力。当出现破坏与否主要取决于最大应力，而最大应力与跌落的不同角度、高度、速度等因素有关。

跌落测试试验中，利用千眼狼PMLAB光学应变测量技术计算产品跌落时的位移、应变、空序位移，观察产品应力变化，在进行计算后，用响应面来表示他们的关系。首先在测试产品中进行散斑标定，并将千眼狼高速摄像机放置地面，观测产品跌落地面时瞬间过程，计算该产品试件所受应变力。

本次手机跌落试验中，对其跌落过程进行运动、位移、应变分析。本次试验可以清晰观察到手机跌落过程，测量分析手机运动速度、位移和应力参数变化。试验分析数据结果可帮助企业优化产品结构设计，提高其抗冲击性能。
