Extraction of Pendulum Model Parameters from Steady-State Slosh Data in Diaphragm Tanks

This study proposes a new experimental approach to extract pendulum model parameters from spacecraft propellant tank slosh data. The novelty of the approach is in the utilization of steady-state triaxial force measurements at the support points of the tank under sinusoidal excitation. This approach...
