Design framework for DEM-supported prototyping of grabs including full-scale validation

The design of machinery for handling granular materials relies mainly on empirical methods and in-house engineering knowledge. This traditional approach provides incremental improvements that are often limited. Advancements in simulation and optimization can offer a promising alternative approach. Most of the research involved in improving or...

DEM particle upscaling for large-scale bulk handling equipment and material interaction

Purpose: The development of bulk material handling equipment can be accelerated and made less expensive when testing of virtual prototypes is adopted. However, the modelling of a grab unloader requires a large volume (77 m3) of iron ore pellets, making the computational costs prohibitive. This paper investigates the extent to which the...

Co-simulation framework of discrete element method and multibody dynamics models

Purpose: Bulk material-handling equipment development can be accelerated and is less expensive when testing of virtual prototypes can be adopted. However, often the complexity of the interaction between particulate material and handling equipment cannot be handled by a single computational solver. This paper aims to establish a framework for...

Virtual prototyping of grabs: Co-simulations of discrete element and rigid body models

This dissertation has investigated whether a combination of DEM and MBD can be used for a reliable and accurate environment for predicting grab unloading performance. A grab is a type of bulk material handling equipment used for unloading materials such as coal and iron ore from vessel to shore. Both a grab and iron ore pellets have been...
