Abstract
This is essentially a report of the final phase of a major study undertaken for the Caterpillar Technical Center, Peoria, Illinois to determine to a high degree of accuracy the bucket/load weight of an excavator under dynamic conditions.
It was quite remarkable that a relatively simple solution was obtained using a least squares approach (as opposed to using a highly non-linear optimization method) considering that there are a total of nine unknown moments and cross moments of inertia of the bucket/load together with the unknown location of the center of mass and the bucket/load weight in the range of 1200–1650 kg which was finally computed to an accuracy of about 0.15%.
