For solving precise measurement problem of quality, centroid and centroidal deviation, put forwards a measurement method by using force balance. Based on quality/ centroid and centroidal deviation measurement principle, use special mechanical equipment and high precision weighting sensor to measure irregular model and analyze technology method of reducing error. The analysis results show that the system has high measurement precision, with practicability, which can be used for high precision aviation dynamic model quality feature measurement.
