研究了多个刚体和弹性体耦合系统的振动特性 ,构造了满足自共轭条件的耦合多体系统特征值问题的正交增广特征矢量 ,并用正交的增广特征矢量级数精确描述了耦合多体系统对任意激励的响应
The vibration characteristics of a number of rigid-body and elastic-body coupling systems are studied. An orthogonal augmented eigenvector of the coupling multi-body system is established, which satisfies the self-conjugate condition. The orthogonal augmented eigenvector series Coupled multi-body system response to arbitrary excitation
