Abstract
The influence of processing rigidification area on dynamic performance of the structure is often neglected in dynamic modeling, while the uniform approximation of modal parameters is a major objective in modeling and model amendment. Two key issues, the establishment of objective uniform approximation model and the analysis on sensitive parameters for model amendment, are studied in this paper. Using the experimental data of two bending metal sticks in reduced scale, the research developed the modal parameters object model of the metal sticks to describe accurately two tested results of the structural response, that is, the natural frequencies and the vibration modes. The main sensitive parameters of model amendment selected through analysis of influencing factors are preliminarily identified as the bending radius and the processing rigidification area of the metal stick.关键词
