Trifilar Pendulum - Mass Moment of Inertia Measurement

Printed n-fold edge markers were attached to the platform to enable automated tracking. The provided Python-based software processes the recorded video to extract the oscillation period and compute the corresponding MoI using standard trifilar pendulum relations. For each configuration, multiple repeated measurements were performed, and the dataset includes both individual trial results and aggregated statistics.

The data demonstrates that the system provides reliable MoI measurements for moderate and high inertia values, with increasing measurement error observed at lower inertia levels due to reduced sensitivity and greater influence of experimental disturbances. The dataset also illustrates the impact of imaging conditions and suspension characteristics on tracking performance and measurement accuracy. All files are structured to allow full reproducibility of the experimental setup, including hardware fabrication, data acquisition, and post-processing.

The repository can be used to replicate the validation results, assess alternative tracking approaches, or adapt the system for related applications in spacecraft testing, robotics, and laboratory-scale dynamics experiments.
