Analysis of the Dynamic Response of A Liquid Rocket Under Seismic Waves
Year: 2024
Type: article
Abstract: By adopting time history method in software ANSYS, dynamic response of a liquid rocket was analyzed when it was suffered from earthquake wave TAFT and EI, and the displacement and stress of the rocket were calculated. The result showed that the liquid rocket swung along the acting direction of the earthquake wave. The higher the position of rocket, the larger the swing, and the maximum displacement located on the top of the rocket, and the maximum stress located at the support places on the rear part. The higher the earthquake magnitude, the larger the swing, and the larger the maximum equivalent stress. The rocket has the possibility to fall down and damage in structure under a strong earthquake over 7 grade.
