Development of a Low Cost Automatic Modal Hammer for Applications in Substructuring

On the robust experimental multi-degree-of-freedom identification of bolted joints using frequency-based substructuring

“…In further studies, the experimental procedure can be improved by using more sensors at the interface to improve the VPT and using an automatic impact hammer [14], to better control the impact positions. To get statistically relevant results for a parameter study, large measurement campaigns are necessary.…”
