摘要

为了研究某姿控发动机双层结构燃料贮箱在升空过程中振动冲击对贮箱的影响,利用流固耦合理论对空载和充液两种条件下的贮箱进行了模态分析、频率响应分析和冲击响应分析。计算出了两种条件下贮箱的模态频率、模态振型;获得了两种条件下贮箱的频率响应特性;得到了两种条件下贮箱冲击响应曲线。

关键词： 贮箱; 流固耦合; 模态; 频率响应; 冲击

Abstract

To predict influence of the rocket shock and vibration on the propellant tank of attitude control engine, modals, vibration response and shock response have been analyzed on two cases with liquid-solid coupling theory. Modal frequencies have been get on two cases, vibration response and impulse response characteristics have been obtain on two cases.

Key words： tank; liquid-solid coupling; modal; vibration response; shock
