摘要: 空间绳网是一种新型的在轨捕获技术，对解决日益紧张的空间环境问题具有重大意义。基于有限元法，将绳网离散为若干绳段单元，通过对单元的受力分析，推导得到了空间绳网的动力学模型。应用罚函数法建立了绳网与目标的碰撞动力学模型。采用ABAQUS有限元软件建立了空间绳网与捕获目标的仿真模型，并实现了捕获过程的动力学仿真，提出了空间绳网捕获效果评价指标，重点讨论了绳网对于不同目标捕获过程的差异。仿真结果表明：空间绳网与球体目标的碰撞力最大，对于正方体目标包裹性最好，并且碰撞后正方体目标的速度和位移增量最大。Abstract: Space net is a new on-orbit acquisition technology, it is of great significance to solve its increasingly tense space environment problems. Based on the finite element method, the space net is discretized into several rope segment elements. Its dynamic model is deduced through analyzing the force of the elements. The dynamics model of the collision between the space net and its acquisition target is established with the penalty method. Their simulation model is established with the ABAQUS finite element software, and the dynamics of the acquisition process is simulated. The evaluation index of the acquisition effect of the space net is put forward. The difference between different targets in the acquisition process of the space net is discussed in detail. The simulation results show that the collision force between the space net and the spherical object is the largest, the encapsulation of the cube object is the best, and the increment of the velocity and the displacement of the cube object after collision are the largest.
