产品样机生产完成后,总体负重比其他同类产品有所
减轻,经过人机设计后的背架由不同身材的消防员通过实
际背负进行测试(见图8),主观舒适度评价均非常好。样 机喷射时间85 s,喷射距离10〜12 m,总质量为29.3 kg 。

Abstract: In order to improve the shortcomings of the existing pig
gyback foam fire extinguishing equipment products such as unrea
sonable structure , poor human- machine experience and potential
safety hazards, the applicable crowds and man-machine in t eraction methods were studied , a modular design concept was proposed ,
and by the design of water tank and cylinders modular as well as the back frame design, a backpack-type multi-functional foam fire extinguishing equipment was designed. As a general- purpose air
respirator, it can also be “deformed ” into a knapsack foam fire ex tinguish! ng device. Through finite element analysis and physical in~
spection, the results show that the product has advantages such as high back comfort , good safety, easy to escape and multi-use of one machine.
