摘　　要：汽车安全带作为乘员安全保护的关键零部件,随着整车不同工况的耐久之后,部分紧固点会出现十分严重的力矩衰减,乘员的安全将存在潜在隐患。分析了力矩衰减的影响因素,重点从紧固件的不同结构状态进行了研究,通过对比试验得出弹簧垫圈是导致力矩衰减的主要原因;并进行实车路试验证,取消弹簧垫圈后力矩衰减有较大的改善。As the critical component of occupant's safety protection,the seat belt is serious torque attenuation at some fastening points after the endurance of the vehicle under different working conditions,and there are potential dangers to the occupant's safety.The influencing factors of torque attenuation were analyzed,focusing on the study of different structural states of the fasteners.The spring washer is the main cause of the torque attenuation through the comparison experiments;and the actual vehicle road test verifies that the torque attenuation has been greatly improved after the spring washer is removed.
