Abstract:This article is a liquid crystal display cushion packaging research. 80% of electronic products fell from collision damage most of the R & D personnel often spend a lot of time and cost for products related to the quality of the experiment, the most common structure is falling and the impact of the experimental test. This method is reliable, but there are many disadvantages: high cost; it is difficult to observe the phenomenon of the process; poor reproducibility; can not be reasons for that; ...... not easy to observe the internal features of LS-DYNA using the product to open touch ago, to address these issues, related to the object of simulation can be greatly reduced, as well as costs associated with R & D cycle. The use of ANSYS finite element analysis software module of the fall (DTM), the establish of LCD cushion packaging system, the finite element model of the model, the sutra, falling Angle, which fell by surface such as color chart or accurate quantitative dynamic display of the form, have no time impact analysis of different high stress and strain distribution, such as the biggest drop, stress concentration in contact with the ground, and the Angle of the maximum stress on display in the contact with the liner, and proposes suggestions on sutra, optimize the structure of cushion packaging.
