A Study on Impact Simulation of 3D Vehicle-occupant Multibody System |
| |
| Abstract: | The three-dimensional model of vehicle-occupant multibody system is constructed according to impact dynamics and multi-body dynamics in this paper. The software named SVC3D (3D Simulation of Vehicle Crash) is developed on the basis of the model. The simulation results of SVC3D in comparison with those of test prove that the model is reasonable and the software is correct. Simulation research into passive safety of vehicle-occupant multibody system is carried out using the software and the conclusions with directive significance are drawn in the paper. |
