【摘要】：目的设计绿色环保的液晶显示器缓冲衬垫,并对其受跌落冲击时的缓冲效果进行有限元分析。方法采用瓦楞纸板折叠成形的方式对液晶显示器的缓冲衬垫进行绿色设计。在ABAQUS有限元软件中建立液晶显示器和缓冲衬垫的实体模型,通过有限元软件模拟液晶显示器运输过程中角跌落的冲击响应,分析缓冲衬垫的缓冲效果。结果角跌落冲击过程中,等效应力云图表明衬垫跌落角处变形较大,应力集中,显示器跌落角处最大应力达到1.293 MPa,但未超过材料的屈服极限。冲击加速度计算结果表明,以1 m的高度跌落时,显示器上易损件的最大冲击加速度为748 m/s2,未超过液晶显示器的许用脆值。结论瓦楞纸板折叠成形的环保缓冲衬垫满足缓冲包装要求,能有效保护显示器抵抗跌落冲击。
[Abstract]:Aim to design a green liquid crystal display cushioning liner and analyze the buffer effect of liquid crystal display under drop impact by finite element method. Methods the buffer pad of liquid crystal display was designed green by corrugated board folding. The solid models of liquid crystal display (LCD) and cushioning liner were established in Abaqus finite element software. The impact response of angle drop during the transportation of liquid crystal display was simulated by finite element software, and the buffer effect of buffer pad was analyzed. Results during the angular drop impact, the equivalent stress cloud diagram shows that the stress concentration is high and the maximum stress at the drop angle of the display is 1.293 MPA, but does not exceed the yield limit of the material. The calculated results of impact acceleration show that the maximum impact acceleration on the display is 748 m / s ~ 2 when the height is 1 m, which does not exceed the allowable brittleness of liquid crystal display. Conclusion the environmental protection cushioning pad for corrugated board folding can meet the requirements of cushioning packaging and can effectively protect the display against drop impact.
