Title: Rollover Test,Simulation and Analysis for Bus
Abstract: Invasive deformation is one of the main causes of passenger's casualty in bus rollover accident. Rollover test is the most effective method to verify superstructure strength of bus body and passive safety. This paper puts forward a method analyzing defects of bus structure based on rollover test and simulation. Combining real vehicle rollover test with numerical simulation,the method analyzes the deformation of bus structure invading the occupant survival space and the change process of energy and acceleration in the rollover. An experiment of real bus rollover was used for testing the method. The finite element model of bus was created with software Hypermesh and rollover process was simulated with the model. With the real test and simulation results,defects of bus structure were detected and measures of improvement were obtained.
