Experimental Study on Impact Force Identification on a Multi-Storey Tower Structure Using Different Transducers

This paper presents the identification of both location and magnitude impact forces applied on different positions a multi-storey tower structure using types transducers, i.e., an accelerometer, laser Doppler vibrometer, triangulation displacement sensor. Herein, model-based inverse method is exploited to reconstruct unknown based various recorded dynamic signals. Furthermore, superposition approach employed identify location. Therein, it assumed that several are simultaneously potential locations structure, while only one has non-zero magnitude. The purpose then detect impact. influence hammer tip materials for establishing transfer function investigated, where concluded with harder leads more accurate function. An accuracy error proposed evaluate reconstruction precision. Moreover, effect sensor type studied, shown proximity between dominant factor in force reconstruction. In addition, efficacy transducers studied localization, demonstrated reducing degree under-determinacy by combination system responses same can improve localization accuracy.
