## 弹簧振子运动仿真

Abstract Spring damper mass system is the vibration of a simple model, through the analysis of the model to explore the vibration of simple motion law, and the motion simulation and motion graph is realized through the programming.
Spring oscillator under undamped state, by simple harmonic vibration of a continuous reciprocating motion, and in a state damping movement will continue to decay until it stops.When only considering the viscous damping, the motion of the spring oscillator with the attenuation law of underdamped condition, the motion of the spring oscillator amplitude according to the geometric attenuation attenuation. When the spring in series or in parallel, using the equivalent stiffness, to calculate the cycle and the frequency of the movement, it is concluded that in series or in parallel with the equations of motion.
The simulation program is the use of Visual C++6.0 development platform, to achieve by calling the Turbo C graphics library C language program.

Keywords: spring, damping, vibration, programming and simulation.

1.离散系统与连续系统

(1)质量（包括惯量）模型只具有惯性。
(2)弹簧模型只具有弹性，其基本质量可以不做考虑。
(3)阻尼模型既不具有弹性，也不具有惯性。它是耗能元件，在做相对运动时产生阻力。 弹簧振子运动仿真:http://www.lwfree.cn/jixie/20190918/39474.html
