摘　　要：载人登月飞行器组合体不同于传统的航天器,不仅具有大柔性的特点,还需要进行大过载动力飞行,各种动力学效应的相互耦合使其动力学特性十分复杂。以"星座"计划的登月飞行器组合体为对象,基于有限元方法初步研究其结构的模态特性和主要连接部段的动态响应特性,并对比分析了两舱和三舱构型载人飞船对组合体动态特性的影响。Different from traditional spacecraft combination, the manned lunar landing spacecraft combination is not only highly flexible, but also subject to an overloaded flight, which would introduce an interaction of multiple dynamic effects. The lunar landing spacecraft combination of the Constellation program is taken as an example. The modal parameters of its configuration and the dynamic responsive characteristics of its main connecting sections are preliminarily investigated by using finite-element-method. As a supplementary, the influences of two-module and three-module configurations on the combination＇s dynamic performance are compared.
