摘　　要：汽车安全带性能检测是国家强制性要求,但是现阶段试验室检测过程中在人、机、料、法、环方面都存在着大量浪费和不规范现象,致使现行试验室检测效率低下且检测质量监督不完善。统计分析试验室现状,绘制汽车安全带性能检测价值流现状图,找出各检测工序存在的生产浪费以及可优化流程。以精益思想为指导,建立拉动式检测模式,绘制完成价值流未来图,并建立价值增值体系。依据价值增值体系和价值流未来图的要求,分别从现场保障、质量保障、均衡化检测保障以及良好的外部协作方面提出改善措施,实现汽车安全带性能均衡化检测。性能检测证明,单批次样品检测周期由37.8天降为14.5天,人员犯错率保持在0.1%以下。The performance test of automobile safety belt is a national mandatory requirement.However,At present,there is a great deal of waste and non-standardization in all aspects of the testing processes,including aspects of personals,machines,materials,methods and the environment,resulting in inefficient testing and poor supervision of testing quality in the laboratory.The statistical analysis is carried out for current status in laboratory,the current value stream map of vehicle safety belt performance testing is drawn,the waste existing in each inspection process and the problem of unsmooth flow between processes are investigated.Under the guidance of lean thinking,a“pull testing”mode is established,the future map of value stream is drawn,and a value-added system is established.According to the requirements of the value added system and the future map of the value stream,improvement measures from 4 aspects are proposed,including on-site guarantee,quality guarantee,balanced detection guarantee and good external cooperation,realizing the balanced detection of automobile safety belt performance.Performance tests prove that,the testing period of single batch of samples is reduced from 37.8 days to 14.5 days,and the error rate of personnel remains below 0.1%.
