【Abstract】 This paper performed the strain measurement of sea-30projectile-fuse system under the high shock environment duringlaunch, with the help of the "hard-wire" technique. The strain curvesof four positions were obtained. Special test experiment projectile as-sembles and gun barrel were instrumented with peak-reading pressuretransducer and strain gauge. The proper positions were discussed forsticking strain gauge. Three kinds of feasible measuring schemes wereraised and measurement precision was analysed. The measured resultswere very useful for structurally dynamic analysis and malfunctionanalysis of projectile-fuse system.更多还原
