Abstract

To verify the working performance of the energy absorption device, CAE simulation software is used to simulate the working process of the energy absorption device. Firstly, the three-dimensional modeling software is used to establish the three-dimensional model of the energy absorption device, and then grid division software is used to divide the established three-dimensional model. Finally, the simulation calculation is carried out in the CAE simulation software. The results show that the speed of the high-speed stone with a diameter of 110mm is reduced from 22.3m/s to 10.2m/s under the action of the energy absorption device, and its energy is reduced by 81.5%. The working effect of the energy absorption device meets the expected requirements. This study provides a great reference value for the design of energy absorption devices.
