The difference between the space and the earth environment has significantly influenced the shape accuracy of the antenna reflector surface. With the increasing demand for the aperture of the antenna reflector, gravity has become one of the main factors that restrict the accuracy. In this paper, a new method for pretension design considering the effect of gravity is proposed. The design surface can be well restored to the ideal surface in orbit. Meanwhile, this method can avoid flipping antenna reflectors or extensive experiments for modification during ground adjustment. Then, the feasibility and effectiveness of the design method are validated by several numerical simulations. Moreover, the results are compared with the previous method and the differences have been discussed in detail. Finally, the effects of cable radius, cable length, and elastic modulus of the mesh reflector have been researched, respectively.

考虑重力影响的可展开网状天线预紧设计与分析

空间与地球环境的差异显着影响了天线反射面的形状精度。随着对天线反射器孔径的要求越来越高，重力成为制约精度的主要因素之一。本文提出了一种考虑重力影响的预紧设计新方法。设计面可以很好的恢复到轨道上的理想面。同时，该方法可以避免在地面调整过程中翻转天线反射器或进行大量修改实验。然后，通过多次数值模拟验证了该设计方法的可行性和有效性。此外，将结果与以前的方法进行了比较，并详细讨论了差异。最后，电缆半径、电缆长度的影响，
