Product drop tests present users with unique parameters for simulation and analysis. The Drop Test module further enhances an ANSYS LS-DYNA license by adding a complement of loads and conditions tailored specifically for such analyses.
Three frames from a Personal Desktop Assistant (PDA) drop test performed in ANSYS LS-DYNA with the Drop Test Module added. The initial impact (top) was calculated as being dropped from a height of 1,829 mm (approximately six feet). The secondary impact (middle) exhibits separation of the PDS's batteries from the main housing. The bottom image displays the rebound of the secondary impact exhibited by the device in the simulation.
