To properly compare blast effects on armored vehicles from test-to-test or test-to-simulation, appropriate instrumentation capable of surviving harsh mechanical loads without drift, biasing, or saturation is required. High fidelity computer modeling is increasingly being used to predict performance of blast test designs and results prior to full-scale testing. Correlating simulation to test data can aid in increasing confidence in the models to further inform test planning and interpret test results. However, it is difficult to collect consistently accurate data that can be compared across test-to-test and test-to-simulation with the current instrumentation used during testing. Recent advances in accelerometer design must be evaluated and, in lieu of acceptable performance, a new isolator system must be developed. A multi-axis input environment must be considered as few (if any) locations of interest within vehicles generate uniaxial loading.
