Abstract

From a view of human safety and product improvement, precise and reliable calibration facilities are the index of industrial development. In NML (National Measurement Laboratory), shock accelerometer is calibrated by comparing to a reference transducer with acceleration range from 1000 m/s² to 10000 m/s². For the Taiwan's industrial demand of low shock calibration and decrease the inconvenience due to transfer the standard from foreign primary shock calibration Lab. NML prepare to develop a low shock calibration system during 2009. We set up two simulations to confirm the ISO 16063-13. First simulation is to set up a simple pendulum instead of rigid body motion, and second one is to generate shock waveform using a shaker. Two realistic simulation results show the feasibility of the constructing primary shock calibration system and provide a well experiment to our future work.
