Design and finite element simulation of elastic-plastic secondary collision test rig

In this paper, there are many troubles in the study of secondary collision of flexible structures, and it is not enough to rely on the support of theoretical knowledge. Equivalent experiments and data analysis and calculation are needed to further verify. Of course, the secondary collision of different flexible structures, their own structural stability, life span and other factors affect the experimental results. In order to more intuitively analyze the secondary collision phenomenon, a set of experimental equipment using rigid ball collision beam is reformed. The main research direction of this paper is the effect of the initial velocity and location of the rigid ball on the secondary collision. From the experimental data analysis, when the initial velocity of the rigid ball is different, the times and time interval of secondary collision phenomenon are also different.
