Method of traveling simulation for rubber tire-mounted gantry cranes

摘要

This paper describes a modeling method for simulating the travel characteristics of rubber tire-mounted gantry cranes. The modeling of the gantry frame, tires, and driving motors is introduced, since there are the primary factors affecting thecrane travel performance The dynamic simulation is cased on the Newmark finite element method . Simulation cases for different trolley positions and gantry traveling speeds are developed and compared to experimental results . The effectiveness of thissimulation method is proven by the strong correlation between the simulation and experimental results.
