一种高可靠无人值守天气雷达天线座介绍

文中介绍了一种结构设计合理、维修与安全设置完善、人机关系考量全面的方位/俯仰式天线座,虽然设计定型已经20多年,但其设计理念对当今的天线座设计仍有一定的参考价值.该天线座在方位机构与俯仰机构中使用相同的预应力转盘轴承,以此独特的结构形式有效地解决了天线座的高刚度与紧凑的结构问题.LRU(现场可更换单元)设计有效地解决了天线座的快速维修问题,从而保证了天线座的运行可靠性和运行寿命.该天线座实现了无人值守的全年连续运行.

Introduction to the Highly Reliable Antenna Pedestal of an Unmanned Weather Radar

In this paper, an azimuth/elevation type antenna pedestal is introduced, which has the advantages of reasonable structure design, good maintenance and safety setting and friendly human-computer interface. This type of pedestal had been designed for over 20 years, its design philosophy could still be used as a good reference for modern antenna pedestal design. A slewing bearing is used to meet the requirements of both high stiffness and compact structure. LRU(line replaceable unit) design has the advantage of quick maintenance, thus guarantees pedestal reliability and service life. This pedestal can continuously work for a year without operator.
