Abstract
• Virtual prototyping technology is showing strong strength inthe rail vehicle. A new high-speed truck is designed with UG,NASTRAN, ADAMS. Using UG, a bogie’s 3D model is built ,and put the model into PATRAN and FEA by NASTRAN.Dynamic simulation is made in ADAMS/rail. The result issatisfied, and make good consistent with the road test data. Thisvehicle type are running in China.
• Key word: Virtual prototyping technology, High speedrailway vehicle, CAD, FEM, Dynamics simulation

1. Introduction
• Chinese rail need faster, more comfortable vehicles.• New type high-speed truck need short design time,the
technology have some difficulty.• Virtual prototyping technology be an efficient method
in design.• This article introduce the design works of new type
high-speed truck using virtual prototyping technologyby UG, NASTRAN, ADAMS software.
