| 摘要: |
| 针对空间飞网系统任务设计需求，研究飞网牵拉模式对系统展开性能的影响。建立空间飞网系统拉出展开过程动力学模型，并通过地面试验对比验证了模型的有效性。面向任务需求建立空间飞网系统评价指标，针对四、六点牵拉模式，采用有限绳段方法对飞网系统进行建模仿真。模型中保持绳网质量和初始发射能量一致，对评价指标的分析结果表明，在六点牵拉模式下，飞网系统飞行性能指标和力学性能指标有明显提高，但能量利用率和系统可靠性小幅下降。 |

| Abstract: |
| For the problem in the mission design demands, the influence of the drag mode on the deployment property of the space net system was investigated. The dynamic model was set up and verified by ground test result. Evaluation criterion of space net system was set up to meet the mission demands and the impact that the drag mode brought in was studied through a finite element method. The simulation models, in which mass of the net and initial projection energy were kept the same, were built based on the finite segment approach for four and six points drag modes. Simulation result of the evaluation criterion indicates that the system flight performance indexes and the dynamic evaluation criterions are improved in the six points drag mode, the energy utilization rate and system reliability, however, show minor decrease. |
