Considering the geometric nonlinearity of cable structures and the high-degree coupling of nodal displacements,a reasonable optimization method is essential in order to improve the surface adjustment efficiency of cable antenna.The equilibrium matrix and flexibility matrix of double-layer cable-net structures were partitioned based on the topology.The gradient formula of surface error to the tensile forces of tension ties was derived in derivative form.The infinite norm of surface error gradient was used to...
