At one time it was considered imperative to collect high frequency accelerometer data for accurate analysis. As a result current FMVSS regulations and SAE J2570 require the use of accelerometers with damping ratio of 0.05 or less (designated as undamped). This prevents the use of damped accelerometers for regulated channels. Damped accelerometers can provide comparable data and in some cases better data than undamped accelerometers, as long as they meet specific minimum requirements. To collect the most useful data, damped accelerometers should be added to the tool box of transducers used by crash test facilities.
