A Finite Element Model for the Free Drop Test of the Monitor Packed by Cushioning Materials

완충 포장한 모니터의 자유낙하시험을 위한 유한요소모델

This paper deals with the finite element model of the monitor for the simulation of directional free drop tests such as backward, sideward, edge and vertex drop. The model was made for an unconditional stable solution for the explicit integration algorithm. The general behaviors at the time of impact were found to well correlate with the actual situation in terms of acceleration, displacement, contact force and stress of monitor components even though the experiment of the associated drop is performed for the validity of the model.
