摘要
本文用基于ＫＢＭ法的摄动法研究大阻尼二自由度非线性振动系统（ｉ＝１，２）的渐近解．井考察了二自由度大阻尼Ｖａｎｄｅｒｐｏｌ方程组，所得结果与数值解对照，吻合较好．
In this paper, the non-linear vibration system with two - degree of freedom at the situation of finite large damping is studied by means of perturbation method based on KBM method. The paper also studies Van der pol equations with two - degree of freedom at the situation of finite large damping and compares them with numerical solutions. The comparison shows that the result by this method coincides well with mumerical solut tions.
