摘要：

In order to reduce the vehicle occupant injury under blast wave, a multi-parameter optimization method was proposed for the vehicle hull underbody structure and occupant restraint system. The simulation for the occupant response was based on the arbitrary Lagrange-Eulerian and fluid-solid interaction methods, which was then calibrated by explosion test. An optimization mathematical model for occupant's leg force and neck bending moment was established, and the thickness, material and locations of vehicle underbody and occupant restraint system were set as design variables. A dimension reduction technique, namely, factor analysis based multi-parameter optimization, was exploited to cut down the sample space of the optimization mathematical model precisely and reasonably. The Pareto set of optimization model was calculated by the proposed methodology, which could get the design scheme of vehicle underbody configuration and occupant restraint system for minimizing occupant injury. © 2016, Editorial Office of Journal of Vibration and Shock.
