| 摘 要： | Aim To study the influence of restraint system performance
upon the occupant's response during impact, and provide a scientific base for occupant
restraint system design. Methods In the light of basic theory of
multibody system dynamics and impact dynamics on the basis of classical theory of impact,
R-W method is adopted to construct the vehicle-occupant system model consisting of
fourteen rigid bodies, thirty seven DOFs and slip joints for the simulation. A software
named SVC3D(3-dimensional simulation of vehicle crash) is developed in the FORTRAN
language. Results The results of simulation have a good coincidence with
those of tests and the restraint system with low elongation webbing and equipped with
pretensioner provides better restraint effect for the occupant. Conclusion The
model of vehicle-occupant multibody system and SVC3D are suitable for use. Occupant should
be belted with low elongation webbing to a certain degree and occupant restraint system
should be equipped with pretensioner.
