摘要
针对当前座椅耐久性测试系统的可视化效果不佳,无法观测到测试设备的位置状态和座椅的受力状态,设计了基于LabVIEW的座椅可视化测试系统。该系统应用PCIe-6320的NI板卡进行数据采集和脉冲输出。运用LabVIEW建立系统的上位机监控界面,增加了设备的姿态监控界面以及力值可视化界面。通过系统测试的结果表明,该系统能够对测试设备的姿态进行实时监控,无明显卡顿现象,设备横、纵位移的极限值分别为1100 mm和250 mm,当接近位移极限时,系统自动进行急停并报警。力值可视化界面能够根据采集的力值进行可视化展示,以初次试验位移-力值变化曲线与其损失22%强度后变化曲线作为上下阈值。当位移-力值曲线在其阈值内时,该座椅的耐久性能满足要求。
Aiming at the poor visualization effect of the current seat durability test system and the position state of the test equipment and the stress state of the seat cannot be observed,a seat visualization test system based on LabVIEW has been designed.PCIe-6320 NI DAQ was used to acquire data and pulse output.The system’s host computer monitoring interface was built by LabVIEW and added the equipment’s position monitoring interface and force value visualization interface.The results of the system test showed that it can monitor the posture of the equipment of the test on real time and there was no crash with the system.The limit values of the horizontal and vertical displacement of the equipment are 1100 mm and 250 mm respectively.And we can be warned in advance if the displacement exceed the maximum and the system would be turned down in time.The force value visualization interface can visually display according to the value of the collected force.The upper and lower thresholds of the curve are established based on the displacement-force value curve collected for the first time and its 22%loss curve.When the displacement-force value curve is within its threshold,the durability of the seat can meet the requirements.
