爆炸场振动装置的设计与数据分析

Vibration device of blast filed design and data analyse

本文介绍了一种灵巧的爆炸场加速度存储测试装置,该装置用于测试记录爆炸场建筑振动信号。它由传感器、模拟适配调理电路、AD变换器、存储器、控制器、接口电路、电池等组成,具有体积小,微功耗,抗高冲击等特点。该装置成功记录了爆炸冲击对建筑体产生的振动加速度信号。分析数据得到了爆炸冲击波作用建筑体产生的加速度信号和建筑体在冲击作用后产生的自激加速度。记录数据对了解建筑物在爆炸冲击波作用下的响应提供了依据。

This paper introduces a smart acceleration storage device. It can measure and storage the acceleration of blast wave filed. It is made up of sensor, adaptive amplifier, A/D converter, memory, controller,interface circuit, and a power source. It has the traits of small size, low power consumption, capable of working under high impact pressure of blast wave etc. The device records the acceleration signals of blast wave filed successfully. Acceleration of building generated by exploding blast wave and natural frequency of building get from data. The recorded data provide valuable basis to understand building impact of blast wave.
