A drop test system includes support members offset from each other and having corresponding tracks, a lifting rod bridging the support members and having rod ends adapted to engage with the tracks to move along the tracks, and a pair of spiral cams adapted to rotate in unison and positioned to engage with and reciprocally lift and drop the lifting rod as the spiral cams rotate. The spiral cams each have a perimeter shape that includes an abrupt section and a curved section that connects to opposing ends of the abrupt section with a smooth curvature. The lifting rod is adapted to ride on the perimeter shape of the spiral cams and gradually lift and drop a unit under test (UUT) as the spiral cams rotate.
