摘　　要：目前对航天器共振轨道特性的研究还非常不完善。为此,对频率为0.5的航天器典型共振轨道理论进行了补充,分析了共振轨道的参数转换模式,提出了共振轨道物理平面方程的直接参数描述方法。对单段共振轨道机动在典型任务中的应用进行了仿真分析,分析对比了共振轨道机动与传统轨道机动的优缺点。同时,通过仿真计算,对共振轨道周期特性进行了研究。研究发现,共振轨道等效速度增量是随时间尺度参数的改变进行准周期变化,而并非严格的周期变化,这一点与文献[3]中的研究结果有所不同。The research on resonance orbit characteristics of spacecraft is still uncompleted. This paper renews the theory of resonance orbit whose frequency is 0. 5,meanwhile,a direct way for the transfer between physical parameters and the new orbit parameters has been brought forward by analyzing the model of parameters transfer of resonance orbit. A computer simulation and an analysis of resonance orbit used in typical missions have been done to compare the advantages and disadvantages between resonance orbit and traditional orbit. By computer simulating,a research on periodic characteristics of resonance orbit has been done. It shows that the scales of resonance orbit＇s acceleration changes quasi-periodically with the parameter time scale which is different from the results in documentation [3].
