| Abstract: | In the non-linear conservative system,the spring pendulum has simple structure and typical motion characteristics.In this paper,the motion equation of the spring pendulum system is obtained through the theoretical analysis of the Lagrangian equation,and the motion is decomposed in the radial and tangential directions.The spring pendulum demonstrator and experimental software are designed by using image processing technology to visualize the motion track and time sequence diagram The trajectory drawn by the software is in good agreement with the theoretical results. |
