Abstract

In order to predict the modal of a composite leaf spring in a light bus and estimate if the resonances among the modal of the composite leaf spring and the excitations will occur or not，the finite element model for the modal analysis of the composite leaf spring was established by using ABAQUS software. The computational modal analysis for the finite element model was carried out and the modal of the composite leaf spring was predicted according to the result of the computational modal analysis. Then the experimental modal analysis for the prototype of the composite leaf spring was carried out. The veracity of the prediction modal and the correctness of the finite element model are validated by the comparison between the prediction modal and the results of the computational modal analysis. According to the modal analysis results，the composite leaf spring can avoid resonances. The relationships among design variables and the first-order modal frequency of the composite leaf spring are respectively analyzed by using the finite element model，which has been validated. The analysis results indicate that choosing 0°ply orientation，choosing composite that possesses lower density and choosing higher fiber volume content can reduce the possibility of resonances. The research results in this paper can significantly reduce the risk and the cost in the development of composite leaf spring.
