Dynamic Force Identification Based on Subsection Integral Method

摘要：

　　Dynamicforce identification is one of the key scientific issues for structural health monitoring research.Structural response and input force can be expanded in the known basis functions using moving least squares method.The identification problem of dynamic force was transformed into determining the combination coef ficients of basis functions, which decreased the unknown parameters and promoted computational efficiency.Then, the formulation with the integration equation of motion instead of the differential equation of motion used will greatly simplify the numerical computation.Numerical simulation indicates that the algorithm can be identified for various forces efficiently and accurately.
