Hot Spot Formation in Mock Materials in Impact Sensitivity Testing by Drop Hammer

Propellants, Explosives, Pyrotechnics, 2017
AbstractPowder and granulated sugars were exposed to the drop hammer impact test configured with 120‐ and 180‐grit Si/C sandpapers. The sugars were selected as mock materials for HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine). The drop heights ranged from 24.2 to 40.7 cm.

Multiple Reference Impact Testing for Bridge Assessment with Drop Hammer

Advanced Materials Research, 2012
A new drop hammer was designed and used for multiple reference impact testing of two bridges. The drop hammer utilizes a multiple-rebound control system for successfully applying a single impact with repeatable high-level force for bridge testing. Signal analysis results indicate that the drop hammer provides a higher signal-noise ratio and a better ...

On the prediction of impact noise, X: The design and testing of a quietened drop hammer

Journal of Sound and Vibration, 1986
Part V in this series showed that the technique of predicting overall noise levels ( L eq per event) from vibration levels in a drop hammer produces surprisingly accurate results, allowing a good estimate of the contribution of each component to the overall noise.
