摘要
本文研究了多自由度非线性振动系统的主振型和主振动。文中采用一种新方法来求解非线性振动系统的主振型,并用近似解析法求解系统的主振动。文中给出了一些新结果。
Prineipal modes and principal vibrations of nonlinear vibration systems withmany degrees of freedom are studied in this paper. A new method is used tofind principal modes of nonlinear systems, and approximate methods are used tofind solutions to principal vibrations, together with some fresh results.
