Abstract
This paper proposes an algorithm for determining structural changes for modifying natural frequencies of a structure in a prescribed manner using Frequency Shift Combined Approximations (FSCA) approach. This algorithm is based on the reduced basis method, natural frequency sensitivity analysis and Taylor series expansion. The application of this algorithm to a truck body finite element analysis is described. Natural frequency modification of the finite element model is shown to converge to satisfied results. The proposed algorithm is easy to implement and is suitable for structural dynamic modification and optimization in many engineering applications.
