Surface segmentation design is a conceptual problem in the structural design of large radio telescope antennas. Before performing surface segmentation optimization, a weighting level set topology optimization method is proposed for the antenna backup supporting structure from the viewpoint of continuum topology optimization. With the help of weighting level set topology optimization, a clear and compact backup supporting structure is acquired. Taking the optimized topology backup supporting structure as the design basis, a surface segmentation optimization scheme is presented and extended to the full aperture. By employing this method in the conceptual surface segmentation design of two large radio telescope antenna applications, the effectiveness of this method is easily illustrated.

表面分割设计是大型射电望远镜天线结构设计中的一个概念性问题。从连续拓扑优化的角度出发，在进行曲面分割优化之前，针对天线后备支撑结构提出了一种加权水平集拓扑优化方法。借助加权级别集拓扑优化，可以获得清晰紧凑的备份支持结构。以优化的拓扑备份支持结构为设计基础，提出了一种曲面分割优化方案，并将其扩展到整个孔径。通过在两个大型射电望远镜天线应用的概念性表面分割设计中采用此方法，可以轻松说明该方法的有效性。
