摘要

摘要: 为了研究汽车动力总成悬置系统与悬架系统的振动耦合程度,建立了包含动力总成悬置子系统和悬架子系统的耦合系统数学模型,提出了一种基于能量的模态耦合分析方法。计算了某汽车动力总成悬置系统与悬架系统的耦合程度,算例的计算结果表明,汽车悬置系统与悬架系统在第一阶和第七阶模态中耦合程度较高。

Abstract: In order to explore the vibration coupling degree between the hanging power unit of an automobile and its suspension system, a mathematical model of the vibration coupling system containing the hanging power unit and the suspension system is established, and a modal coupling analysis method is proposed. As an example, the vibration coupling degree between the hanging power unit and the suspension system is calculated. The calculation results indicate that there is a high vibration coupling degree between them at the first modal and the seventh one.
