Dynamics of Large Mining Excavators

By James Watmough


In this report, parametric and non-parametric regression models and their suitability to determining the mass in the bucket of large mining excavators are compared. Although the problem of determining the force on the bucket teeth could be modelled in a similar fashion, it is not clear that there is a single force acting on the teeth and not a more complex contact between the bucket and the ground, so the report focuses on the problem of determining the payload mass. The parametric model is found to be the better approach, because although a detailed model of each type of machine must be developed, an exact measurement of the model parameters is not required, and the model requires far less data for training that the non-parametric one
