摘要

土工结构振动台模型试验除了需采集常规的加速度、位移、应变信号外

还需采集模型场地土中振动孔隙水压力、动土压力等信号

由于同步采集的动态信号的多样性和复杂性

一般的振动台信号采集系统难以满足这样的多种动态信号同步采集要求。基于传感器融合技术和虚拟仪器技术

研发了一套适用于多种类型信号输入的动态信号同步采集系统

可实现80通道动态信号、18通道数字信号的同步采集、回放和频谱分析等功能

并具有界面友好、使用维护方便等特点。

Abstract

The signals that need to be collected from the soil-structure shaking table model test besides the routine acceleration

displacement and strain

also include vibration pore water pressure of the model site soil

dynamic earth pressure and some other especial signals.For the dynamic signals acquired synchronistically have diversity and complexity

the general shaking table signal acquisition system can hardly realize the real-time and synchronous signal obtaining.Therefore

based on virtual instrument technology

a dynamic signal acquisition and analysis system suitable for synchronous acquisition of many types of signals was developed

which enables simultaneous acquisition of 80 channels’ dynamic signals as well as 18 channels’ digital signals.In addition

this system can achieve the functions of spectrum analysis and signal playback. At the same time

it also has a friendly interface and the predominance of convenient usage and maintenance.
