| 摘 要： | 功率流矩阵传递分析法对复杂隔振系统的分析存在很大的困难,有限元动态分析却可以解决绝大多数结构的振动问题.本文将机械阻抗融入有限元,提出了一种全三维的功率流计算新方法.并应用此方法,基于双层隔振系统模型,分析了上下层隔振器刚度、上下层隔振器阻尼及基座刚度对功率流传递的影响,提出了一些有用的结论.

| Abstract: | Calculation of power flow of complex vibration isolation system using matrix transfer method is difficult.However,the finite element method may solve most engineering vibration problems.For engineering purpose,the mechanical impedance is combined into the finite element method,then an approach of calculation of the power flow of three dimensions is formed.With this method on a two stage vibration isolation model,the influence of elastic mounting stiffness,damping and base rigidity on power flow transmission... |
