Abstract: . Nuclear fusion energy is a promising new energy, This vacuum environment in nuclear fusion reactor is provided by the precision vacuum vessel, which also provides a support structure for the installation of internal components of the fusion device. In this paper, the impact response of double layer vacuum chamber inner wall under transverse impact load is experimentally studied to manufacture the high quality vacuum chamber. From the drop weight experiments, the vacuum chamber wall under five groups of different impact energy is analyzed, and the impact response displacement, and energy absorption rate of the sample are compared and discussed. The experimental results show that the impact force and impact response displacement increase with the impact energy, and the error also increases. The influence of rib plate in the vacuum chamber inner wall on impact response displacement is analyzed. With the increase of the damage deformation of the vacuum chamber wall, the rebound amount of the impact block cannot increase linearly with the impact energy. The actual situation is simulated with software, and the results of experimental and simulated energy absorption are compared and explained.
