Liu, H.; Mi, W.; Zhao, N., and Feng, Y., 2015. Modeling and simulating the operation of the harbor portal crane.

As more and more attention has been paid to energy saving, consumption reducing of the port in order to realize the concept of a green port, the number of experts and scholars devoted to the research of energy saving technology in port machinery is increasing. Generally, due to the busy port operations, port machinery could not be divorced from the operating line solely for research. Moreover, the use of real port machinery would impose a high cost for research. Therefore, it was necessary to look for a low-cost, high-precision research platform. In this article, we established a mechanical model, motor model and control model by simulation software based on a real portal crane. And we integrated these three models into the whole simulation platform, providing an energy saving research base by simulating the hoisting and luffing operation of the port crane and analyzing the power change and energy consumption in the hoisting and luffing process. The results of the simulation showed that the simulation platform can completely meet the requirements for portal crane energy saving research.
