The Study and Application of Structure Experimental Analysis System Bas ed on Highspeed Data Acquisition and Real-time Signal Analysis

本文采用计算机多线程技术实现了实时信号数据采集分析 ,开发出了一种基于高速数据采集和实时信号分析的结构实验分析系统。该系统具有对给定结构进行振动噪声等信号的实时信号测试分析和进行实验模态分析等功能 ,具有广泛的适用性和良好的及时扩充功能。

The technique of multi thread was ad opted to realize real time analysis of signal acquisition, and structure experi mental analysis system was developed based on it. The system may be used to do r eal time signal test and analysis of vibration and noise signal and modal analy sis of structures. And the system has widespread applicability, good extended fu nction, treatment ability and cost performance.
