NOL铜球加速度计《NASA N66—21122》本报告描述了美国海军军械实验室(NOL)研制的几种球破碎器和峰值读出加速度计。应用它们就能以简单方法记录复杂的冲击,冲击谱的一些概念也适用。讨论了调整铜球加速度计记录冲击峰值的新方法。十个这种型式的加速度计就可复盖大约30至450000g这一冲击范围。相应的自然频率范围为244CPS至14800CPS。
NOL Copper Ball Accelerometer NASA N66-21122 This report describes several ball shredders and peak readout accelerometers developed by the U.S. Navy’s Ordnance Laboratory (NOL). Applying them makes it easy to record complex impacts, and some concepts of shock spectra apply. A new method of adjusting the impact peak of a copper ball accelerometer is discussed. Ten of these types of accelerometers cover an impact range of about 30 to 450,000 g. The corresponding natural frequency range is 244CPS to 14800CPS.
