Abstract

Traditional we use the standard accelerometer to calibrate the dynamic force. The standard accelerometer was calibrated by vibration standard machine. However, the calibration condition is not as the use condition. So we need to develop a dynamic force calibration method, which was the same condition as used. This paper describes a new method of dynamic force calibration. Now we measure the acceleration by a laser Interferometer. Traceability for force is realized via the measurement of acceleration with laser-Doppler-interferometers and the determination of the dropping masses. This paper introduces the structure and the working principle of the equipment, performance parameters and the uncertainty evaluation. This paper also compares the data between the accelerometer and laser-Doppler-interferometer.
