摘要: 首先,分析了一具有特定非线性函数的二阶类摆系统的解的性质;进而,针对具有一般非线性形式的二阶类摆系统,利用微分方程的定性分析方法讨论了其总体性质,并由此给出了估算其临界阻尼的充分性条件.改进了Leonov等人的工作.

Abstract: First,the properties of solutions of a typical second-order pendulum-like system with a specified nonlinear function were dicussed.Then the case with a general form of nonlinearity is considered and its global properties were studied by using the qualitative theory of differential equations.As a result,sufficient conditions for estimating the critical damp are established,which improves the work by Leonov et al. -
