MODELING AND OPTIMIZATION DESIGN OF COMPLEX ELASTIC COUPLED VIBRATION ISOLATION SYSTEM

复杂弹性耦合隔振系统是在多层隔振系统中考虑中间筏体和基础的弹性而形成的一类隔振系统,提出了关于这类复杂隔振系统子结构建模的新方法,并用该方法建立了二维复杂弹性耦合隔振系统的动力学方程。并在此基础上进一步提出了一种新的基于小生境的自适应遗传优化算法,运用该算法对二维复杂弹性耦合隔振系统基于系统功率流传递的最优化设计。

Complex elastic coupled Vibration isolation system is a kind of multi-stages isolation system considering on the influences of elastic raft and non-rigid base. A new substructure method is presented to build the dynamic equation of this kind of isolation system. Moreover a new adaptive hybrid genetic algorithm was proposed. Based on which power flow optimization design of a kind of complex elastic coupled isolation system carried out.
