Study of Drop Test Parameters Using Design of Experiments

Various products such as refrigerators, mobile phones, televisions, washing machines, remote controls, telecommunication and military equipment, etc. are subjected to drop tests to assess their fragility and impact tolerance. It is difficult and expensive to understand the effect of various parameters that affect product performance during the test. Finite element simulations using LS-DYNA® effectively help to understand the effect of these parameters. However, as the number of iterations required can be large, design of experiments approach is used in combination with finite element simulation to extract suitable information. Moreover, it is observed that most of the parameters are common across drop test simulations of different products.
