Application of Virtual Prototyping to Simulation of Vehicle rail Coupling of AERORail Structure

Abstract:

The prestressed cable AERORail structure is different from the common bridges, more fundamental experiments are required especially for its dynamics behaviors. Virtual prototyping technology (VPT) is an economical and timesaving way to study this new structure. After an analysis of the feasibility and the merit, this paper introduces the flexible model theory and method with VPT software. Based on the 1∶15 model experiment, the simulation process and skills with 1∶1 model are presented and the vertical displacement and acceleration time history curve is obtained. Finally, the paper presents a summary of the model skills for the flexible cable rail structure.

Key words:AERORail structure; virtual prototyping; flexible body; simulation; time history curve
