Abstract

The existing approaches of domestic and foreign researchers are considered in the field of simulation of the loading of bus frames with the calculation evaluation of the power structure for compliance with the requirements of passive safety during rollover. The criteria and the main ways to improve the quality of computer models, to reduce the duration of calculations are determined. The fundamentals of the methodology for computer simulation of bus tests are presented and described for compliance with the requirements of UN Regulation No. 66. An example of  the use of the proposed guidelines is given in the preparation of a computer model of a suburban bus to conduct a calculation evaluation of the superstructure using the ANSYS LS-DYNA finite element analysis software system. Preparation of the model is performed using the Ls-PrePost program.

Keywords
