摘要起爆药的机械感度是指起爆药在受到撞击，摩擦，针刺等机械作用时爆炸的难易程度。本实验目地是测定一些常用起爆药（如硝酸肼镍）在一定的粒度和形状下的的机械感度，探索粒度与感度的关系，并且在获得数据后建立起爆药的机械感度库；实验中主要是测定撞击感度，采用升降法，即根据起爆药的性质，先确定一个初始刺激量，选定一个步长，在初始刺激量下开始实验，根据规则确定每次的刺激量，最后得到起爆药在不同粒度下的撞击感度数据。64746

从数据及计算结果上看，起爆药的撞击感度较高，并且在一定粒度范围内撞击感度随着粒度的增大而增大。

Title    The establishment of a common detonator library mechanical sensitivity                               

Abstract

This goal will be to determine some of the commonly used primary explosive, such as nickel hydrazine nitrate) under a certain size and shape of mechanical sensitivity, explore the granularity and the relationship between the sensitivity, the detonator after get the data to establish library mechanical sensitivity; Experiments mainly determine the impact sensitivity, the lifting method is Bruceton method, namely according to the nature of the primary explosive, first determine the initial stimulus quantity, selected a step, start experiment under the amount of the initial stimulus, the detonator from the first ignition start recording, Then ignition, reduce the stimulation of a step, don't angry, add a step to stimulate, same case do 25 and record data of the experiments; Finally got the initiating explosive impact sensitivity under different granularity data.

The detonator from the data point of view, the impact sensitivity is higher, and the impact sensitivity within a certain particle size range increased with the increase of particle size increases.

Key words：size，mechanical sensitivity，Bruceton method
