Low-frequency mechanical environment simulation of large space structure based on 6-DOF kinetic platform
-
摘要: 空间结构的大型化、复杂化导致其固有频率降低、模态密集,也使得低频动力学环境对其结构特性的影响日益严重。文章以大型环形网状可展开天线反射器为例,研究了大型空间结构的低频力学特性及其失效模式,分析了航天器动力学环境的低频特点,提出了基于六自由度运动平台的低频多轴力学环境模拟方法。Abstract: The effect of the low frequency dynamical environment on a large space structure is increasingly a serious issue. This paper studies the low frequency mechanical characteristics and the failure mode of large space structures, with a large-loop-net-antenna as an example, and analyzes the characteristics of the low frequency environment of spacecraft. The simulation method for the low frequency and multi-axis mechanical environment is put forward based on the 6-degree-of-freedom kinetic platform.
