Abstract:
This publication presents a multibody simulation (MBS) of a drilling rig using the Simscape environment
of Matlab/Simulink. Simscape is included in Mathworks graphical programming environment Simulink. It
allows the simulation of physical systems using a Model-based design (MBD) approach, providing a
graphical block diagramming tool containing various block libraries. The developed model allows a
parametric simulation of rig models, considering the different dimensions and the simulation of different
movements. Furthermore, the model includes a simple representation of the soil that monitors the subsoil
concerning the machine's movement and operating conditions. Given the short time needed for running the
simulations using Simscape, the presented model is suitable as a developing tool for fast checks of the
drilling rig's stability stand.
