【摘要】 介绍一种同时考虑数量和位置优化的传感器布置算法——基于两步有效配置法的传感器优化布置方法。该法首先通过弹性波传播原理确定特定结构的传感器布置极限间距并初步确定检测所需传感器数量,然后,以传感器布置极限间距为约束条件,采用有效独立—驱动点残差法对传感器进行优化布置。针对特定检测系统,以桥梁结构Benchmark模型为例,验证了上述传感器两步优化配置法的有效性。计算表明,该法能有效地解决传感器优化配置问题。更多还原

【Abstract】 This paper proposes an Effective Two-Step Arrangement method for sensors optimization.The number and the location of sensor optimization are realized by the following two steps.First,calculate the utmost distance of sensors on a special structure by the principle of elastic wave propagation and determine the preliminary number of sensors;second,optimized sensors placement is ultimately determined by Effective Independence Driving-Point Residue(EFI-DPR) method which use utmost distance above as a constrained condition.In the bridge benchmark model case study,it shows the validity of two-step sensors optimization arrangement under some one special detection system.更多还原
