多维力疲劳试验台监控系统的设计与实现

Monitoring and Controlling System in Multi-component Force Fatigue-Testing Plaftorm

为了实现对大型结构件的疲劳试验,模拟其实际工况,采用六自由度平台的结构形式设计成多维力疲劳试验台。针对该疲劳试验台的功能和控制要求,介绍了采用研华工控系列产品的计算机监控系统。数据采集及控制输出均采用研华输入输出模块,上位机在VC++平台上编写监控程序;下位机采用嵌入式Linux实时系统,对疲劳试验台做六自由度协调控制。该疲劳试验台是国内首次将六自由度平台用于大型结构件的疲劳试验,目前已投入使用。

In order to simulate the factual working condition of large-structural parts,Stewart platform is designed as the Multi-component Force Fatigue-Testing Platform.This paper introduces monitoring system,which based on ADVANTECH facility,to meet the function and control requirements of this fatigue platform.Data acquisition and real-time control are all modules of ADVANTECH.Monitoring program is written on upper computer by VC＋＋;lower computer use embedded Linux real-time system,in which coordinate control of 6-DOF is achievable.
