摘要 为分析飞轮扰动对卫星框式结构动态特性的影响,针对卫星薄板结构采用行波方法建立其动力学模型,在此基础上,运用行波法与子结构法相结合的方式建立了卫星框式结构行波动力学模型,进行了结构动态特性数值仿真并与有限元结果进行对比.结果表明,采用行波方法计算卫星框式结构动力学响应准确有效,并且能够在中、高频段获得更精确的计算结果. In order to analyze the effects of flywheel disturbance on dynamic characteristics of satellite frame structure,the dynamics model of satellite thin plate was established by travelling wave method in this paper,and then the travelling wave dynamics model of satellite frame structure was established by combining travelling wave method and sub-structure technique.The simulation on dynamics characteristic of the satellite frame structure was carried out,and simulation results were compared with FEM results.It is showed that travelling wave method is accurate and effective in calculating the dynamic response of satellite frame structure,and it is more accurate than FEM results at mid to high frequencies.
