摘要
以计算多体动力学理论为指导,以船舶柴油发电机组的抗冲击研究为背景,建立了柴油发电机组的多体动力学以及线性隔振系统模型,并通过实验验证模型的正确性;在此基础上构建机组的非线性隔振系统,并对机组额定工况以及冲击条件下隔振系统的动态特性进行分析,结果表明非线性隔振系统较线性隔振系统有良好的隔振效果。文中的建模与求解方法较数学建模与求解简单易行,对隔振器选型与安装、非线性隔振器的参数化设计与优化、其它船用机械的抗冲击研究奠定了一定的工程应用基础。
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.
