关于冲击摆的计算

The calculations about ballistic pendulum

本文介绍了有关单摆与复摆的计算方法、产生加速度的原理、冲击加速度的调整与测量方法及其误差分析。冲击摆是在工厂条件下校准加速度计的一种装置。对于低于５０００ｍ／ｓ２的冲击加速度，其稳定性和准确度都很好；若加速度波形为半正弦波，其测量综合误差优于５％。

This Paper describes the calculations about mathematical (simple) and physical (compound) pendulums, the principe of produced acceleration, the adjusting and measuring methods and the error analysis methods of acceleration. The ballistic pendulam in a calibration vnit of piezoelectrical acceleromers in factory conditions. For the shock shock accelerations less than 5 000 m/s2, it' s stability and accuracy are all very good. If the form of acceleration in a half-sine form, its synthetie error of measurement in betler than 5%.
