Abstract

The paper discusses the problem of the mobile crane movement prediction
in real-time during the operation of the crane. Dynamic and kinematic
models of the crane are created to solve this problem. The models form
the digital twin that can be used to facilitate the crane operation. As
the crane can move rather fast, the crane dynamics, rather than
kinematics, becomes more important in its movement prediction. However,
in order to be calculated faster than real-time the crane model should
be simplified. The paper considers an example of the mobile crane for
which two models are developed: the detailed reference model and the
simplified model for faster than real-time calculations, which includes
the dynamic and kinematic equations. We implemented both models as C
programs. Experiments are made in order to compare the accuracy and the
calculation speed of the simplified model with respect to the reference
model.
