Non-parametric force identification from structural response
AbstractForce identification is the process of determining the temporal description of excitation to a system. Since direct measurements of forces are almost impossible for many cases, an experimental procedure called the sum of weighted acceleration technique has been developed. The approach directly identifies the unknown force without knowing the model details of the structural system. This approach usually uses experimental data to determine the weighting coefficients by least squares formulations. This paper provides analytical procedures for determining the weighting coefficients based on either mode shapes or finite elements. The development is general but applications are restricted to one-dimensional structure to simplify the presentation.
