Analysis and Design Optimization of Heavy Goods Vehicle for Child Pedestrian Safety
This research addresses the analysis and design optimization of a new passive safety concepts for Heavy Goods Vehicle (HGV) by the installation of additional component under a bumper called “lower bumper stiffener and “an airbag on the front panel of HGV to minimize the child injuries.The HGV-to-child collision was simulated by the MADYMO crash analysis solver, in which the HGV collision at the speed of 25km/h against the child model with several variations of postures and facing directions was simulated.The scope of the analysis is limited to the duration of impact between the HGV and the child model so this will ignore all the post impact cases.The design parameters of this concept were varied by the adoption of the Response Surface Method techniques with the use of Latin Hypercube Sampling (LHS) and the child bodies injuries of head injury criterion (HIC), thorax cumulative acceleration (C3ms), and peak femur loads were taken as the objective functions.Due to the diverse parameters and constraints of the initial conditions and the injury thresholds, the design problems were solved by multi-objective optimization by the Weighted Injury Criterion (WIC) that combined all these injuries.Based on the results of the design optimization, the potential of these child pedestrian safety design concepts were discussed.
