Abstract
In this paper, dynamic simulation study of the running performance of the AGT vehicle with the single-axle bogies are described to show the characteristics of the single-axle bogie in realistic situation. The multi-body dynamics modeler, DADS, is used to build the dynamic model of AGT vehicle with single-axle bogies and this is used to demonstrate the vehicle motion in actual guideway. The target AGT vehicle consists of front bogie, rear bogie and body. The each bogie consists of bogie frame, rotating frame, guide wheels and running wheel. Twenty seven (27) rigid bodies including sprung mass are used for the vehicle modelling. Suitable joints that connect each rigid body are selected and applied to realize the actual movement. The multibody dynamics code is used to built the dynamic model of AGT vehicle with single-axle bogies and this is used to demonstrate the vehicle motion in actual guideway. It is demonstrated that the vehicle dynamic response can be obtained in realistic situation by using multibody dynamics code, that is useful for designing both vehicle and guideway.
