Vehicle Impact Simulation for Curb and Barrier Design. Volume 1: Impact211 Simulation Procedures

摘要

The objectives of this study were to perform computer simulation of vehicle-curb211u001eand vehicle-berm impacts, to characterize the behavior of a wide range of vehicle 211u001etypes after such impacts, and to produce design and evaluation trajectory data 211u001efor use by NJDOT engineers. The impact simulations performed involved a wide 211u001evariety of vehicle types and several different curb and berm configurations that 211u001eare typical to those in use in the state of New Jersey. Simulation results from 211u001ethis research, primarily in the form of vehicle bumper trajectory plots, were 211u001eproduced to supplement existing curb-impact vehicle trajectory databases. Vehicle 211u001etrajectory data of this type is typically used to determine appropriate set-back 211u001edistances for guide rails (railings) that are located near curbs. Such railings 211u001emust be positioned s that vehicles impacting curbs do not overshoot the top of 211u001erailings placed nearby.
