Abstract
In order to investigate the payload cabin safety after falling impact in near space mission, based on the theory of nonlinear dynamics, the collision model of payload cabin is established by Ansys, and the Ls-Dyna analyzer is used for the simulation calculation to obtain the mechanical properties of buffer device during the impacting, and the structural mechanical response of the main structure of the load cabin. The result shows that the payload cabin impacts the ground with a speed of 7m/s and an acceleration of 3g which can meet the safety requirements. The cushioning effect of the buffer device can protect the payloads from the impact and is beneficial to recycle the internal devices. According to the recovery conditions of the payload cabin and internal devices after the falling impact experiments, the results are in good agreement with the conclusions obtained from the simulation analysis. The proposed simulation method is of great significance to the design and optimization of payload cabin in near space.
