机械弹性车轮有限元计算与试验模态的相关性研究
Correlation between the finite element calculation and experimental mode of a mechanical elastic wheel
摘要
Abstract
To meet the requirements of response prediction and dynamic optimization design, the vibration charac-teristics of a new mechanical elastic wheel ( MEW) were studied by combining the finite element calculation and testing experiments. The frequency of the vibration modes and the corresponding vibration modes were obtained through the finite element analysis. In combination with the analysis results of parameter sensitivity and the test modes, the finite element model of MEW was updated. On the basis of the theory of inner product correlation, cor-relative analysis of the modal parameters that were obtained from the updated finite element calculation and experi-ments was conducted. Results from the correlative analysis proved the validity of the finite element modeling and up-dated method. The precision of the updated finite element model was improved to the point where the calculation re-sult could accurately reflect the structure characteristics of the MEW, providing a reference for further study on dy-namic optimization design of wheel structures.关键词
