A validated co-simulation of grab and moist iron ore cargo
Replicating the cohesive and stress-history dependent behaviour of bulk solids
The traditional design approach of grabs and other bulk handling equipment consists of manufacturing and testing physical prototypes. A novel design approach is to use a co-simulation of MultiBody Dynamics (MBD) and Discrete Element Method (DEM), in which the virtual prototype ...
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 ...
Industrial scale validation of DEM supported grab design
Completing the design cycle
This paper describes the DEM simulation supported design approach leading to a breakthrough in grab design. More specifically it aims to demonstrate the full design cycle including evaluation of the grab prototype on full-scale in realistic operational conditions and comparison w

Design of grabs for coarse material
Enhancing the penetration and cutting depth for limestone
Due to the constant growth of global maritime shipping, the optimization of grabs used for unloading bulk carriers is more and more relevant. Especially for a coarse material like limestone, the average payload can be improved, by altering the grab design. It is suggested that th

Design of a hybrid grab mechanism
Enlarging the minimum bulk unloading capacity by torque addition
Grabs are essential in the process of unloading a bulk carrier by grabbing bulk material such as iron ore from the cargo hold. Due to varying operational conditions, the consistency and the amount of payload can vary significantly. One of the largest varying operational condition

Bulk materials such as iron ore transported by bulk carriers are commonly unloaded by the use of grabs. The unloading process is time consuming and increasing the unloading capacity is of big importance for terminals. A validated co-simulation developed by the TU Delft in coopera
