基于乘用车内部凸出物试验测评方法研究

目前,国内外有关汽车内部凸出物试验的标准中均只将假人头部作为参考指标;而正面碰撞法规和C-NCAP(2021版)中均将假人的头、颈、胸、骨盆、腿等部位损伤值作为衡量汽车安全性能优劣的重要评价指标。本文通过滑台碰撞试验方法,对汽车内部凸出物试验测评方法进行研究;结果显示:假人的头、颈、胸、腿部均受到不同程度的损伤;尤其是95th假人的骨盆位移量过大,造成假人下半身受到损伤更为严重。因此,本文建议乘用车内部凸出物试验测评方法中,应适度考量假人多个部位及其损伤指标,旨在不断完善我国汽车安全标准体系,进一步提升汽车安全性能,更好地保护驾乘人员的乘车安全。

Research on Test and Evaluation Method Based on Interior Fittings of Passenger Car

At present,the standard of interior fi ttings test at home and abroad only regards the dummy head as the assessment index.However,the head,neck,chest,pelvis,leg and other parts of the dummy are taken as important evaluation indexes to evaluate the safety performance of vehicles in frontal crash regulations and C-NCAP(version 2021).In this paper,the dynamic test and evaluation method of vehicle interior fi ttings is studied by the sled crash test method,the results show that the head,neck,chest and legs of the dummy were damaged in different degrees;Especially,the pelvic displacement of 95th dummy is too large,which makes the lower body of the dummy more seriously damaged.Therefore,it is suggested that multiple parts of the dummy and its damage index should be considered appropriately in the test and evaluation method of passenger car interior fi ttings,so as to continuously improve the automobile safety standard system in China,further improve the vehicle safety performance,and better protect the safety of drivers and passengers.
