摘要
三体问题是一类求解十分复杂的物理问题。将三体问题抽象为数学模型,利用Simulink仿真软件对地球、太阳和月球的圆形限制性三体运动过程进行仿真,通过设置合适的初值,得到此三体问题在不同时刻的运动状态,逼真地演示太阳、地球以及月球在相互的万有引力作用下的运动情况,从而便于对三体问题进行观察研究。
The problem of trisomy is a kind of very complex physical problem. The three body problem is abstracted as a mathematical model, and the Simulink simulation software is used to simulate the circular restrictive three body movement process of the earth, the sun and the moon. By setting the initial value, the three body problem in the state of motion of different time, vividly demonstrates the sun, the earth and the movement of the moon in the gravitational interactions. Thus, it is convenient to observe on the three body problem.
