Similarity analysis of ground experiment of three body problem

After the analysis process of similarity on three body problem is studied, a similarity function for measuring the similarity degree in three body problem trails is established. At first how to build a trial on ground is defined then the dynamics model of three body problem is built, and a similarity function for measuring the similarity degree is built. Then a lot of disturbances in the trails are studied in order to figure out the most important disturbance of the trails. Finally a series of simulations are done by computer, and degrees of the influence caused by different disturbances are ranked from highest to lowest. Those results are useful for the design of astronautics three body trails.
