摘要
本文用改进了的L－P法研究了一类保守系统强非线性自由振动问题；在此基础上，用插值摄动法[1]进一步研究了更一般的非保守系统的自由振动问题。算例表明，本文方法是可靠的。
In this paper, using the improved L-P method, the author seeks to solve a class of strongly nonlinear free oscillation problems of a conservative system. On this basis, using the interpolation perturbation method, we progressively study the more general strongly nonlinear free oscillation of a nonconsevative system. Numerical examples are presented. They show that the method of this paper is reliable.
