火工品燃气输出动态参数特性的分析与测试

在查阅国内外有关火工品手册和对使用单位调研的基础上,综合分析现有火工品表征燃气输出威力参量的压力、推力、加速度、温度、位移、速度等的信号特征,给出了输出威力测量值的参数类型、量值大小和频率响应的特性范围.针对各类火工品的输出信号特征,选择相应的传感器、信号调理器和动态分析仪,建立了一套火工品试验动态多参数测试系统,可以实现在一次试验中多物理量同时测量,获取更多的输出参数性能信息,并可以分析各参数之间的相互关系,为火工品输出性能的设计和测试系统的建立提供参考.

Analysis and Test on Combustible Gas Output Dynamic Parameter Features of Initiating Explosive Devices

Based on the research of overseas and domestic initiating explosive device handbooks and the investigation of user units, the signal features representing the combustible gas output power parameters, such as pressure, thrust, acceleration, temperature, displacement and speed, are synthetically analyzed for the present initiating explosive devices. The characteristic quantity ranges about parameter type, amplitude and response frequency are presented. Based on output characteristics of various kinds of initiating explosive devices, sensor, signal amplifier and data acquisition instruments are selected and a multiplexed measuring system of initiating explosive device test dynamic parameter is established. Many physical quantity can be tested at the same time in one test via this system. More information and analyses of the relation between the parameters can be received. These fealures have an important value for the design of initiating explosive device output performances and the establishment of their measurement system.
