Selecting Single Optimal Excitation Position for Spatial Truss Structure's Damage Detection Based on Euclidean Distance

Abstract:

According to characteristics of frequency-intensive on spatial truss structures, maximum isolation each modal is a good solution to this question. Considering this idea, calculating modal weighting coefficients of spatial truss structures through dynamic response expression, mode vector and objection vector can be obtained. An objection function was established based on euclidean distance. When the euclidean distance between mode vector and objection vector minimize, the optimal excitation position can be also received.
