Force reconstruction using force gauges and accelerometers

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Methods of inferring excitation forces from measured accelerometer data have received significant attention in recent years. This paper attempts to combine these techniques with the addition of force gauges to determine excitation forces on a vibrating structure. A mathematical algorithm was derived and applied to experimental data where a known impact force was applied to a plate mounted through force gauges. This experiment was used both to validate the mathematical algorithm and to investigate its limitations. The results show that the applied force for a fixed structure can be reconstructed better than force gauges alone using a combination of force gauge data and free boundary condition modal analysis.
