多支承弹性非保守耦合系统导纳功率流

摘要

利用四端网络分析方法建立了多支承弹性非 保守耦合系统的导纳分析模型，该模型考虑了多支承点相互耦合的影响，研究了通过非保守 耦合元件输入到弹性结构的振动功率流，并通过计算机仿真分析了非保守耦合元件对结构之 间功率流传递的影响，以及支承点相对位置改变对功率流传输的影响，本文提供的方法可用 于一般机械隔振系统分析和评估。%A dynamic model is described for non-conservatively coupled systems consisting of a source machine, four isolators and a flexible supporting structure. Characters of power flow transmitted into the supporting structure are investigated, and numerical calculations are presented to examine the power flow into the supporting structure under various coupling and connection. The approach used in this paper is also useful to isolating system analysis.
