基于最小不可识别损伤模型的传感器优化布置

提出了一种以不可识别损伤最小为目标的传感器优化布置方法。该方法在某种损伤情况下，建立结构的损伤模型，得到任意传感器潜在位置处的预测效应值，将使不可识别损伤模型数目减少到最小的布设方案做为最优方案。考虑到在求解最小不可识别损伤模型的个数的过程中计算量巨大，针对最小不可识别损伤模型个数的求解，编制了相应的优化算法。算例分析验证了此方法原理明确，操作简单，实用性较强。

Optimization of Sensor Layout Based on Minimum Non-Identifiable Damage Models

An optimal layout method of static sensors was put forward in this paper and corresponding algorithm was writterr for computing. Under the condition of some kind of damage, structural damage models were built, strain prediction of sensors on potential position were obtained, minimum non-identifiable damage models were made as the optimal decision. In consideration of the calculated amount was very large in the process of solving the minimum non-identiable damage models, corresponding optimistic algorithm was compiled. It was proved that the method was efficient ＇and ascendant through numerical examples.
