摘　　要：针对新的MPDB碰撞工况,通过整车试验研究了碰撞强度和车辆质量之间的关系、假人损伤的特点和碰撞强度与安全带限力对THOR假人损伤的影响。结果表明,碰撞强度与车辆质量成负相关关系,THOR假人的损伤与碰撞强度成正相关关系。THOR假人的胸部是损伤风险最高的区域,安全带的限力等级是影响胸部压缩量的关键因素。最后基于试验数据分析计算出为减小THOR假人胸部压缩量所要求的安全带限力等级。A vehicle MPDB(mobile progressive deformable barrier)test is conducted to study the relation⁃ship 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.
