Development of Tower Crane Simulation System with Flexible Wire Rope

Based on virtual reality technology, a simulation system for training and checking tower crane operator is developed.In Virtools, an interactive 3D (three-dimensional) visual working environment is built, where an operator can simulate visual tower crane's motion with real operating feeling.By Catenary theory, hoisting rope's mathematics equation is built, and its flexible and swing simulation are studied with the physical functions provided by Virtools.According to relative standards and rules, automatic check and evaluation system is established.Simulation case shows the reasonability of motion and collision, objective and logical evaluation in this system.
