Abstract
With the instruction of computational dynamics of multi-body systems theory, and at the background of shock resistance study on diesel generator of marine, the multi-body dynamics systems of diesel generator and linear vibration isolation system were molded. Then, these models were confirmed by the diesel vibration intensity experiment. Based on these factors, the non-linear vibration isolation system was constructed, then, the dynamic characteristics were analyzed when the diesel generator worked on rated condition and under impact loads. The results indicated that the effect of non-linear vibration isolation system was better than linear vibration isolation system. Compared with the mathematic method, the modeling and solution method in this paper can be easily realized. This method can be widely used in the process of model selection and vibration isolators fixing, in the aspects of parametric design and optimization, and in the shock resistance study of other mechanism.
