摘要:将基于Fisher矩阵的有效独立法(EI)应用到高铁受电弓传感器优化布置当中,分别采用两种不同优化思想得到两种不同的优化方案。首先,运用EI法分别对受电弓主要组成部件逐一优化布置;其次,运用该法直接对其整体进行优化布置;最后,利用四种评价准则对本文提出的两种方案和均匀布置方案进行验证和对比分析,结果表明EI法在结构复杂的受电弓传感器优化布置当中是有效可靠的,且逐一对结构主要部件优化的思想获得模态向量线性独立性更好、模态信息量更大、布设位置更加精确,该思想在工程应用当中具有一定的指导意义。

Abstract:The effective independent method (EI) based on Fisher matrix is applied to optimal sensor placement of pantograph of high-speed railway. Two different optimization methods are adopted to optimize the layout. Firstly, the main components of pantograph are optimized respectively by EI method. Secondly, layout of the pantograph as a whole is optimized directly by this method. Lastly, these two optimization schemes are analyzed and compared by four evaluation criteria. The results show that the EI method is effective and reliable in the optimization of pantograph sensor placement with complex structure. The modal vectors obtained by the optimization of the main components one by one shows the advantages of better linear independence, larger modal information and more accurate placement of sensor. This method is of guiding significance in engineering application.
Key words:effective independent method;optimal sensor placement;evaluation criteria;pantograph of high-speed railway
