In this paper, ANSYS software is applied to determine the material distribution, load transfer path and equivalent sectional dimensions of the conceptual car body model based on the original body shape of engine cars. In terms of the finite element model of the body, the topology optimization is carried out according to the maximum bending and torsion stiffness, respectively. Through comparing the material distribution under different volume fractions and considering at the same time the manufacture feasibility, the initial style of body frame is achieved. Then, as the sectional dimensions of beams is optimized in both size and dimension, parameter matching scheme of the body frame in minimized weight is brought forward under constraints of the strength and stiffness at maximum frontal impact loads that improves the utilization rate of the material. The results suggest that both the design efficiency and quality can be improved greatly by combining topology and size optimization technology at the concept design phase of car body structure.

The strength analysis of bus superstructure was extremely important that the manufacturer must take into account, especially in the maximum stress analysis as well as the construction stiffness. In this study, the finite element (FE) model of an intercity bus superstructure consisted of chassis frame and body structure has been analyzed based on the improved beam joint considerations. The accuracy improvement of beam type element model was performed using the equivalent joint stiffness of T-junction beam modeling, and then compared with shell and volume elements. According to the improved T-junction FE model, the flexible joint stiffness consideration has been obtained, in which the behavioral error was reduced to less than 6%. The FE model of bus superstructure with improved beam joint was then compared to the rigid joint condition in bending, torsion, longitudinal and lateral load cases. The numerical results revealed that magnitude of maximum stress in the improved beam joint model displayed increasing of 11.53 %, 14.11 %, and 18.45 % in torsion, longitudinal and lateral load cases, respectively. However, the maximum stresses reduced in a case of bending with value of 5.72 %. In addition, the value of construction stiffness of improved beam joint model exhibited lower than the rigid beam joint as 44.85%, and 10.68% in the bending and torsion load case, respectively. To improve the accuracy of computer simulation, it will be beneficial to the passenger and the bus structure design and improvement procedure.
