Research on a one-step fast simulation algorithm for bus rollover collision based on total strain theory

A one-step fast simulation algorithm for bus rollover collision is proposed referencing to that for sheet metal forming. This algorithm is based on nonlinear total strain theory and starts with two states, namely the state when collision happens and the state when maximum collision deformation is achieved. First, an initial solution meeting the deformation conditions is calculated by considering the energy conversion relationship during rollover collision. The final deformation meeting the equilibrium conditions is obtained by Newton–Raphson iteration. A case study on the rollover of a typical bus body section is carried out using the proposed algorithm, of which the effectiveness is verified by comparing its results with the ones obtained by LS-DYNA and rollover test.
