铝合金蜂窝结构件原来是经过声阻仪检验合格后才允许装机使用的。在高空高速飞行中,装在某机水平尾翼和冷翼上的蜂窝件,曾连续数次出现撕裂和飞掉蜂窝块的现象,严重影响飞行安全,一度成为需要紧急解决的问题。其中关键之处是如何将粘接强度不够的蜂窝结构件检测出来。显然,仅仅用敲击法和声阻仪进行检测已无能为力了。我们采用的方法是首先进行声阻仪检查,再进行抽负压吸附检查,最后再用声阻仪进行复查。该法甚好,自 Aluminum alloy honeycomb structure was originally tested by acoustic resistance meter before allowing installed capacity. In the high-altitude high-speed flight, installed in a certain level of tail and cold wing honeycomb pieces, there have been several times in a row tear and fly off the phenomenon of honeycomb blocks, seriously affecting the flight safety, once the urgent need to solve the problem. The key point is how to detect the honeycomb structures with insufficient bonding strength. Obviously, just using the percussion method and acoustic resistance testing can do nothing. We use the method is the first of the resistance meter check, and then suction vacuum suction test, and finally re-use of acoustic resistance meter review. The law is good, since
