复合敏感式安全带锁止时间的研究

摘要

针对某型符合国家强制标准GB 14166-2013《机动车乘员用安全带、约束系统、儿童约束系统ISOFIX儿童约束系统》的复合敏感式安全带锁止机构进行了研究，分析其结构组成和运行原理。建立了车感、带感、承力锁止机构的运动方程，获得了锁止机构锁止时间的解析方程。利用ADAMS软件进行锁止机构锁止时间的仿真分析，并与理论解析解进行比较，结果表明，二者锁止时间相近。%This paper presented a locking structure of compound sensitive retractor ,which was in accordance with the Standard GB14166-2013 “safety-belts ,restraint systems ,child restraint systems and ISOFIX child restraint systems for occupants of power-driven vehicles” .The retractor’s structur-al composition and operation principles were analyzed .The equations of motion for the body reactor , belt reactor ,and inclined locking mechanism were established .An analytical model for locking time was obtained .A simulation of safty belt locking time was analyzed by ADAMS .The simulation re-sults are in agreement with the analytical solutions .
