FOPS落物保护结构试验台
|
摘要
FOPS落物保护结构试验台是一种机电一体化的高精度试验台。该试验台主要通过控制系统控制移动横梁装置及落锤提升释放装置运动,将落锤移动到被试设备标记的冲击点上方;通过自动控制落锤提升高度储存能量;通过自动释放落锤使其进行自由落体运动模拟落物对土方机械落物保护结构的动态冲击;通过测量系统测量出冲击部位的瞬时最大变形和最终剩余变形,并进一步分析判定被测落物保护结构是否合格。介绍FOPS落物保护结构试验台的主要技术指标、主要功能、组成原理以及试验流程。
The FOPS test bench is a precise test facility in electric mechanical integra-tion that the test bench moves through actuation of the cross beam and the hammer lift release which shifts the hammer to the impact position above the impact point. By means of the stored energy and automatic hammer release to simulate the falling object impact-ing onto the protective structure of the earth-mover under the test that through the measuring system to have counted the maximal instant deformation and residual set deformation at the impact position before further analyzing and deciding the FOPS qualified or not. The text goes further to introduce key tech indicators, major functions, principles of composition as well as test procedures.
