A New Automobile Crash Sensor Tester 910655

This paper examines how crash sensors are tested and describes a new general purpose impact machine which can be used. The paper describes the pulse shapes in common use (haversine and half sine), pulse accuracy, longitudinal and cross-axis vibrations and pulse durations and how this machine performs these tests. Other tests including pulse angularity, temperature, vibration and other environmental tests. Finally, this paper discusses available sensor test equipment from the standpoint of pulse accuracy, data acquisition accuracy, pulse amplitude and duration capability, coast or dwell capability, the ability to simulate an actual crash pulse, ability to impose cross axis vibrations and the ability to test against a mathematical model.
