Abstract

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.
- pendulum-like system,
- Lagrange stability,
- gradient-like behavior,
- limit cycles of the second kind
