Experimental validation of a fast dynamic load identification method based on load shape function

ZHANG Qing-xia1,3,4,DUAN Zhong-dong2,3,ukasz Jankowski4,WANG Feng1 (1.College of Civil and Architecture Engineering,Dalian Nationalities University,Dalian 116600,China; 2.Harbin Institute of Technology Shenzhen Graduate School;Shenzhen 518055,China; 3.School of Civil Engineering,Harbin Institute of Technology,Harbin 150090,China; 4.Smart-Tech Centre,Institute of Fundamental Technological Research,Polish Academy of Sciences,02-106,Warsaw,Poland )  
A dynamic load identification method was introduced and complemented,in which the force was approximated by using the shape functions in the finite element theory.The computational work was reduced a lot by calculating the weights of shape functions instead of indentifying the discrete load time history and the performance of the deconvolution method in the condition of long sampling time period or high sampling frequency was improved.Moreover,the ill-conditioning of the inverse problem was corrected,and the robustness to noise was strengthened.The numerical example of a continuous beam verifies that the load can be identified precisely by this method under the influence of 5% Gaussian noise pollution in the signals.In a cantilever beam experiment,via the measured structural responses,the method enables the online load identification which is performed repeatedly in a moving time window.
