波浪与发射荷载作用下的海上发射平台运动分析
Analysis of the motion of the sea launch platform under wave and launch loads
摘要
Abstract
To solve the problems associated with fixed locations and the serious threat of falling debris to the safety of people's lives and property during land-based rocket launches,researchers proposed a sea-based launch solution.This paper employed STAR-CCM+software to carry out numerical simulation calculations on a prototype of a ship-shaped sea-based launch platform,examining its motion state under the influence of waves and unsteady launch loads.Unsteady launch loads were applied to different positions on the sea-based launch platform to investigate its rolling motion state and to determine the optimal launch position.The research also delved into the regularity of the impact of the platform's width on its rolling motion under wave action,as well as the effect of unsteady loads on the platform's motion at various rolling angles.The results indicate that the optimal launch point is located at the center of the sea-based launch platform;under different wave-approaching angles,as the width of the platform increases,the amplitude of the sea-based launch platform's rolling motion decreases;to mitigate the impact of the rocket's ascent on the motion response of the sea-based launch platform,the launch is conducted when the launch point is in the rising phase of the platform's rolling motion.关键词
