A ROLLOVER TEST OF BUS BODY SECTIONS USING ANSYS

Abstract

The homologation of buses depends on its behavior during the rollover tests. This paper presents a computer simulation of rollover test on a body section of a structure constructed in order to be used for new bus models. Pendulum test on a bodywork section from Directive 2001/85/EC is used as a test method for rollover test. The geometrical model and the material proprieties are designed through the Ansys 13 software, using a real structure as a reference. The pendulum and the residual space are the other two designed parts for the simulation process, an interconnection being used just between the structure part and the pendulum part. The pendulum velocity is calculated using the equivalent mass of the body section, including the loads of elements which are not part of the structure. The rollover behaviour results should be improved. The next steps will be to verify which properties should be changed to make this improvement.
