摘　　要：伺服系统中的天线转台是保障跟踪的重要组成部分,为了避免天线方位和俯仰飞车导致事故发生,天线转台采取限位保护措施是必不可少的。在某型测控装备天线转台研制设计中,为防止天线方位角和俯仰角超限导致信号缆硬性拉断造装备事故发生,设计了一套天线限位保护装置,采用了电气限位和机械结构保护两种限位方案,在电气限位中使用了接触式行程开关出发电机停车控制信号,机械限位采用了液压缓冲机构,通过两级防护顺次发挥作用,可以有效的对俯仰轴系实现限位防护。实践证明,采用电气及机械的限位措施,不仅保证了俯仰轴系-5°-92°的转动范围,而且有效的进行了限位保护,保障了装备安全运行。The antenna rotating platform is the most important part in servo system. To avoid the occurrence of accident when the platform is rotating, the protection measures should be taken. This paper designs a new protection equipment to protect the signal cable from the accident when the antenna platform is rotating and antenna is beyond the limitation. The design adopts electric protection and mechanical structure protection. The electric protection adopts the special switch to trigger the signal for stopping the car, and the mechanical structure protection adopts hydraulic cushion structure. The antenna platform by the two ways in turn is protected. The results prove that the method proposed can ensure the equipment safety with the rotating range from -5o to 92o.
