- Abstract
In order to reduce head injury in the collision between pedestrian and vehicle, and explore a variety of influence factors of laminated glass on the impact injury. Several laminated glass impact damage effect factors are considered to establish a series of simulation models, crash simulation calculations are conducted using LS-DYNA; In this paper, using finite element model of sedan vehicle, according to EEVC WG17 pedestrian protection legislation and regulations, the finite element model of adult head impactor hitting PVB laminated windscreen was established, and collision simulation analysis was performed using LS –DYNA; secondly, modify related factors of original vehicle laminated glass using HyperMesh, the factors closest to the actual value were obtained. Research results show that ,at the same speed, simply supported constraint form is closer to rubber support constraint form; appropriate size of finite element mesh is 5mm,and it is closest to the actual value; when the friction coefficient is 0.5, it is closest to real value. Under the premise of the same speed, with the decrease of elastic modulus, acceleration curve obtained from the simulation analysis deviates more from that obtained from experiment.
