针对位于椭圆轨道上的绳系系统,利用“圆锥”模型通过仿真研究其动力学运动特性。绳系系统是具有一定面积的主星和子星通过若干根超长的绳索连接而成的结构。基于主星的大面积和绳索的超长度,分别将其建立成两两相连的质量杆和用力连接的小圆柱。在动力学模型的基础上,针对主星和整体系统进行动力学仿真研究。研究表明,系统在椭圆轨道姿态稳定、主星展开正常。在材料范围内较小的绳索伸长使绳索紧绷,省去了展开过程中力的设置。
For the rope system located on the elliptical orbit, the kinematic characteristics of the system are studied by simulation using the “cone” model. Rope system is a certain area of the main star and the sub-stars connected by a number of long rope structure. Based on the large area of the main star and the excess length of the ropes, they are built into two connected mass rods and forcefully connected small cylinders, respectively. Based on the dynamic model, the dynamic simulation of the main star and the whole system is carried out. The research shows that the system is stable in elliptical orbit and the main star is normal. Smaller rope extensions in the material range keep the rope tight, eliminating the need for force setting during deployment.
