The Nonlinear Oscillation of the Spring Oscillator in Two Dimension

BAO Xing-ming ZHOU Zhi-jian YUAN Yu-quan Department of Physics,Sichuan University of Science and Engineering,Zigong 643000,China  
In this paper,two dimension vibrations of two flexible symmetric simple harmonic oscillator were studied.The nonlinear vibration equations were obtained by using the Lagrange function method,then solved them by using numerical method.Results showed that the small vibration of this ideal model was non simple harmonic,and the period of vibration in y direction was inverse ratio to its amplitude,but its wave form could be seen as a similar cosine wave shape which was independent with it.
