Abstract

The
article discusses the problem of real-time prediction of the mobile crane movement
based on the analysis of the dynamic and kinematic models of the crane. These
models form the digital twin that can be used to facilitate the crane
operation. As the crane displacements can be comparable to the load dimensions
and the crane can move rather fast, thus the crane dynamics, rather than
kinematics, becomes more important in its movement prediction. However, in
order to be calculated faster than real-time the model should be simplified.
The article considers an example of the mobile crane for which two models are
developed: the detailed reference model and the simplified model, which
includes the dynamic and kinematic equations. The accuracy and the calculation
speed of the simplified model are estimated with respect to the reference
model. Two models are compared and some assumptions are proposed for building
the models for the faster than real-time calculations required for the movement
prediction of mobile cranes.
