The vortex structure of galaxies has been a focus of scientific research in recent years.Through the research on the formation mechanism of vortex structure,not only the universe and galaxies will be understand,but also the foundation to study the other astronomical phenomena will be more easily.Scholars have made a lot of conjectures in recent years,and lots of works have been done on the mechanism of the formation of vortex galaxies through the research results of cosmic galaxies.But there is no satisfactory conclusion about the formation mechanism of the vortex galaxies until now.The three-dimensional viscous two body problem under a rotating reference system is simulated in this paper,meanwhile a certain theory and a clear image have been obtained.Then the images and the structures of the vortex galaxies are compared and analyzed,and the images are basically consistent.Further,The factors which influenced the galaxy vortex structures through adjusting the size of the parameters have been explored,and some conclusions have been obtained.There are great of value due to the conclusions for us to explore the warpage structure of galaxies.With the continuous development of the means of astronomical observation,the warpage structure of the vortex galaxies has became a universal phenomenon of the universe.Our previous studies have shown that the reason of vortex galaxies is the large scale rotation of its background instead of a relatively isolated system.The evolution of the galaxies seems to be hurricane formation and evolution of the universe on account of the large scale rotation.Through our further researches,it has been proved that the warping structure of vortex galaxies is a result of the inertia force under the large scale background rotation.The galaxies of double particles under the background rotation are investigated in this paper,and the trajectories of three dimensional double particles motion have been analyzed.Meanwhile,the influences of several vital parameters such as magnitude and direction of the angular velocity have been discussed.Results indicate that the relative physical parameters play an important role in the process of the galaxies structure formation,and the fact that the large scale rotation is the basic reason of warping galaxies has been proved.Furthermore,the studies show that the key parameter influencing warping degree of vortex galaxy is the angle between the directions of the spiral galaxy disk and the angular velocity of the background rotation.In addition,the magnitude of the angular velocity of the background rotation is also an important factor in the formation process of the warpage of galaxies.
