Experimental study of fast sealing airbag in simulating tunnel

摘要：

　　Against problems in terms of stability,airtightness and so on of current fast sealing airbag,stability and airtightness of fast sealing airbag in simulating tunnel was studied through combining theoretical analysis and experiment.The ideal viton material is finally found after comparing and analyzing heat resistance,flame resistance,wear resistance,hardness and air permeability of different kinds of rubber.Sealing and wind blocking effects of airbags made from selected material are tested in simulating tunnel.Rate of air leakage and changing rate of wind pressure of each kind of rubber are also determined and further verified,with result that both indexes ofviton material are the least,respectively only 4.25% and 4.66%.
