【摘要】 本文论述了火炸药撞击感度测定中对落锤运动状况进行监测的必要性,介绍了监测落锤运动的方法和装置。在不同的落锤重量、落高和润滑条件下,利用落锤运动监测系统实测了落锤经过导轨上两定点之间的时间间隔将△t(?)与△t(?)理想自由落体相对应的理论计算时间△t进行比较,分析与探讨各种不同因素影响的规律和机理,从而提出撞击感度测定中选择落锤重量、润滑条件的原则。更多还原

【Abstract】 It is necessary to mornitor the motion of hammer in testing the sensitivity of explosive to impact. The method and device for this purpose is presented in this paper.The interval V in which the hammer passed through two fixed points on the guide of drop hammer machine was measured with different hammer weight,drop height and lubricants,and compared with those calculated by free-falling body equation. The principle to select the hammer weight and lubricant in testing the sensitivity to impact is proposed.更多还原
