Modeling the transient drop analysis for a TV in protective crushable foams is considered in this work. The modeling process of different parts and important issues related to them is described in details. Next, the analysis was focused on the effect of two important parameters, namely foam thickness and foam density, on the maximum stress of the TV shell and the board chip. The analysis showed that increasing the foam thickness could protect the TV set from damage. However, this effect is noticeable up to a certain level and after that is not economical. The results also indicated that decreasing the foam density could reduce the maximum stress on TV set by absorbing more energy during impact.
