Structural Dynamic Modification Based on Combined Approximations Method
School of Mechanical and Aerospace Engineering, Jilin University, Changchun, People’s Republic of China
Structural dynamic modification plays an important role in structural dynamic design. This paper presents an algorithm for dynamic modification of the structure, which is based on the Combined Approximations (CA) approach, sensitivity analysis, Taylor series expansion and the least square method. The feasibility of the algorithm is verified by a numerical example and the results show that the algorithm is accurate enough and easy to be implemented.
