Abstract

This paper presents an integrated structural-electrical model of an RTG crane to analyze operational vibrations. It combines a finite element beam structure, non-linear pendulum dynamics, and induction motor models for hoisting and trolley movement. The study includes model reduction analysis for efficiency, demonstrating the ideal number of nodes for the crane arm. Results present the vibrations observed in the crane arm structure due to lifting and lowering cargo, along with the machine variables of the hoisting motor. This illustrates the benchmark for structural vibration control in RTG cranes. © 2025 IEEE.
