在桥梁结构试验或现场检测中,以及在最近提出的智能桥梁结构的研究中,传感器优化布置问题是引起业内的广泛关注的热点问题之一。本文以梁式桥梁结构为研究对象,提出了一套基于传递误差最小准则的传感器优化布置法,并通过实例,得出在给定传感器数目情况下简支梁传感器优化布置方案为均布的结论,该结论与Baruh 和Choe[1]基于插值拟合准则的分析结果完全一致。
In the bridge structure test or field test, as well as in the recently proposed intelligent bridge structure research, the sensor optimization layout problem is one of the hot issues that arouse widespread concern in the industry. In this paper, a beam bridge structure is taken as the research object, a set of optimal sensor placement method based on the minimum transmission error criterion is proposed. Through examples, the conclusion is drawn that the optimal arrangement scheme of the simply supported beam sensor is uniform with a given number of sensors This conclusion is consistent with the analysis results of Baruh and Choe [1] based on the interpolation fitting criterion.
