Abstract: Dynamics simulation of hoisting machinery is very important for making virtual construction system true and assisting real construction projects. Aiming at the simulation of tower crane dynamics, the dynamics module of EON Professional 6.0 software, an advanced development platform for virtual simulation was adopted and the virtual simulation of tower crane dynamics was realized. In the simulation the wirerope was modeled as a flexible body and a virtual construction scene was built to test the overall dynamics simulation of virtual tower crane. The analysis model and the corresponding dynamics equations of tower crane system were structured, and then the simulation of cable swing and cable breaking under special working conditions were achieved. The results show the feasibility of the strategies and methods for overall dynamics simulation of virtual tower crane based on dynamics module of EON Professional 6.0 software with the assistant of dynamics equations, and this approach can be appiled to other hoisting machinery.
