本文叙述了一种新型的大型警戒雷达天线支座结构,这种结构能使装在舰船桅顶的天线始终绕垂直轴旋转。该设计有减轻重量、改善可接近性、便于维修等优点。文中给出了轴角度转换的数学理论。文中还提到已制造经过周密设计的按比例缩小的伺服传动模型,并在实验室摇摆台上对此模型进行了鉴定。本文给出了所进行的动力试验的某些结果。
This article describes a new type of large radar antenna mount structure that allows the antenna mounted on the ship’s masthead to always rotate about a vertical axis. The design has the advantages of weight reduction, improved accessibility, easy maintenance and so on. The paper gives the mathematical theory of shaft angle conversion. The article also mentioned that a well-designed scaled-down servo drive model has been made and the model has been identified on a laboratory swing table. This article gives some of the results of the dynamical tests carried out.
