Nowadays, the transportation vehicles are dominant and growing accord with need using trans portation of Vietnam. The transportation vehicles have many advantages by high speed, running on many routes short, medium and long roads with high quality transport. The bus 29 seats made in Vietnam with large market demand has been the authors using as research subjects. This paper presents the results of Building finite element models of the structure body of bus 29 seats made in Vietnam with 2 calculate models: the frame body (structure model) and the air body (airborne model). The structure body dimensions of the bus are using by technical Scan3D and using the Rapidform software connection with Ansys software to calculate. Therefore, the results obtain save time and more accurately.
