INSTRUMENTATION OF STRUCTURES FOR AIRBLAST AND GROUND-SHOCK EFFECTS
Abstract
The objective was to provide instrumentation, electronic and self- recording, for obtaining air-blast and groundshock loading and response of the structures employed by the various structures projects. Included was installation of transducers, recording of transducer signals, and presentation of the recordings as linearized time-dependent plots of the measured variable in the specified appropriate units. A total of 127 recording channels was utilized; of these channels, 75 were used for electronic recording on magnetic tape, 37 were used for self-recording timedependent gauges, and 15 were peak- indicating gauges. A basic description of the instrumentation employed by the Ballistic Research Laboratories in taking the structural measurements for Projects 30.1, 30.2, 30.3, 31.4, and 31.5 is given. Self-recording gauges for measuring peak pressures, pressures vs. time, dynamic pressures vs. time, and displacement vs. time are described; electronic gauges for obtaining time- dependent records of pressure, dynamic pressure, acceleration, displacement, and earth pressure are described. For each type gauge, details are given on the recording mechanism, transducer element, gauge mount, calibration, and data presentation. A plot of the field layout is also shown.
