【摘要】 以某微型乘用车为研究对象,在ADAMS软件中建立了整车多刚体动力学模型,利用HYPERMESH对副车架和后悬架扭转梁划分网格,并在PATRAN、NASTRAN有限元软件中对它们进行模态分析,生成的中性文件导入ADAMS中建立起整车刚柔耦合模型。在此基础上,以悬架隔振为目的,进行了悬架刚度、阻尼的匹配分析,讨论了匹配结果对路面中高频激励传递的影响。分析结果可以为悬架优化设计提供参考。更多还原

【Abstract】 In this paper,author establishes a muti-body dynamic model for a certain mini-car based on the software of ADAMS.The subframe and rear twist-beam are meshed in HYPERMESH, their modals analysis is completed in the software of PATRAN and NASTRAN.The coupling model of the full vehicle is built in ADAMS with the neutral file exported in the modal analysis.Based on the model,the matching study of the suspension stiffness and damping on the vibration isolation-rate is performed,and the influence of matching results on the high-frequency transfer characteristics is discussed.The results can provide reference for the optimal design of suspension.更多还原
