Dynamic characteristics of vibration power for isolation system with intermediate mass;
具有中间质量结构振动功率流的传递特性
Based on mobility matrices,the control mechanism of little intermediate mass inserting in isolator is studied theoretically,deriving the expressions of the power flow spectra and plotting its curve.
应用导纳矩阵分析法研究了将质量块插入隔振器之间对功率流的控制机理,研究表明,小中间质量与机器及基础之间的耦合作用很弱,每一个支撑点都可以被独立地控制,这样对复杂激励下的平动、转动等控制就有了实现的可能;在越过因加入小中间质量而使系统增加的固有频率后,功率流得到大幅衰减,使附加频率低于需隔振的频域则可获得较宽的隔振范围。
Aiming at several defects of GMDH NN(neural network),this paper has done some improvements on the aspects of preselection of initial variables number,constitute of partial expression,choice criterion of middle variables,stopping principle,and realized it with Matlab language.
