Abstract: In this paper we obtain the kinetic expression of the spring pendulum system through the Lagrange function method.The controlled parameter is the frequency ratio.We present the numerical simulation under different controlled parameters and initial oscillation angle by using Matlab.Moreover,we study the motion character of this system comprehensively and intuitively.

Key words: spring pendulum, frequency ratio, Matlab, numerical simulation
