整车MPDB试验中THOR假人损伤的研究

Abstract

Abstract:

A vehicle MPDB （mobile progressive deformable barrier） test is conducted to study the relationship between crash severity and vehicle mass， the injury features of dummy and the influence of crash severity and seatbelt force limit on the injury of THOR dummy. The results show that the crash severity is negatively correlated with vehicle mass， while the injury of THOR dummy is positively correlated with the crash severity. The thorax of THOR dummy is the part with highest risk of injury， and the level of seatbelt force limit is the key factor affecting chest compression. Finally， the level of seatbelt force limit required for reducing the chest compression of THOR dummy is calculated based on test data analysis.

Key words: MPDB, THOR dummy, crash severity, seatbelt force limit, thorax injury
