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。

关键词: 安全带锁止机构, 锁止时间, 运动方程, 仿真分析

Abstract:

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 structural 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 results are in agreement with the analytical solutions. 

Key words: seat , belt , locking mechanism, locking time, equation of motion, simulation analysis
