The conditions for chaotic motions of some dynamical systems withnonlinear structures are studied in this paper. The relationship between existence of Smale horseshoes and mechanical system parameters is obtained by applying the Melnikov analytical method.%讨论一类非线性结构动力系统混沌运动的条件。利用Melnikov函数法对相应的非线性动力方程进行分析,得出了系统出现Smale混沌运动时系统参数之间的关系。
