中文摘要:
      为了评价电脑主机缓冲结构的缓冲效果,利用高速摄像测量方法,对电脑主机运输包装件冲击实验进行了冲击响应分析,研究了电脑主机包装件中EPE 缓冲垫对电脑主机的防护作用。实验中分别取5,10,15 cm 3个跌落高度,利用跌落冲击瞬间缓冲垫、主机、水平滑台三者冲击作用的瞬态图像,通过采集图像进行处理和分析,得到了电脑主机的位移-时间、加速度-时间曲线以及水平滑台的加速度峰值和衬垫冲击传递率。结果表明,随着冲击高度的增加,电脑主机加速度响应随之增大,缓冲垫的冲击传递率达到50% 左右,显示出EPE 缓冲结构具有显著的缓冲效果。
英文摘要:
      In order to evaluate the cushioning effect of host computer cushion structure, impact test was carried out on personal computer package by using high speed camera photography, and the protective performances of EPE cushion were investigated. Experiments were carried out with three drop heights of 5, 10, 15 cm. A high-speed camera was employed to capture high-speed digital images of the cushion, host, and sliding table during impact tests. The shock displacements and response accelerations of host and sliding table were analyzed using digital image processing technique. The displacement-time and acceleration-time curves of host computer, peak acceleration of sliding table, and shock transmissibility of cushion was obtained. The research results showed that the response accelerations of the host computer increase with the increase of drop height; the shock transmissibility of cushion is at about 50%, which indicates that the EPE cushioning structure has outstanding cushioning performance.
