摘要
当前的行人保护冲击试验设备,发射端长达800 mm左右,无法完成全套的自由运动头型(FMH)试验。为了解决该问题,通过用牛皮纸与小气缸制造成触发开关,在发射气缸前端通过局部压缩气体回收活塞机构,设计了“L”形发射端,长度仅仅有380 mm。研究结果表明,所设计头型发射装置能够进行全套FMH试验,其试验精度可控制在±0.3 km/h之内。所设计的简易FMH头型发射装置结构简单,调节灵活,精度完全满足FMH试验要求,可以用来进行FMH试验及其它小型发射类试验。
For current pedestrian protection test device,the transmitter terminal is about 800 mm long and unable to complete a full set of the free motion headform(FMH)test.In order to solve the problem,by making a trigger switch with kraft paper and a small cylinder,and through the local compressed gas recovery piston mechanism at the front end of the launch cylinder,an"L"shaped launch end is designed,which is only 380 mm long.The results show that the new headform transmitter can carry out a full set of FMH tests,and its test accuracy can be controlled within±0.3 km/h.It is concluded that the simple FMH headform launcher can meet the requirements of FMH test with simple structure,flexible adjustment and precision,and can be used for FMH test and other small launching tests.
