炮瞄雷达天线自动升降机构的设计
摘   要
雷达是一个复杂的电子机械设备，自其诞生之日起，他的不断发展动力就在于与空中进攻性兵器的激烈攻防对抗。在当今现代化战争中，雷达受到的“四大威胁”日益严重，这四大威胁分别是:综合电子干扰、低空或超低空目标、反辐射导弹和隐身目标。雷达天线面积庞大，振子数目较多，相应的运输单元数量也比较多，造成其拆卸、拼装以及阵地转移都很困难，因此迫切要求雷达具有较高的机动性能，以提高雷达的战场生存能力。液压升降是雷达结构中的不可缺少的机构，也是雷达性能和质量的重要保证。现代战争对雷达系统的机动性能要求越来越高，尤其重视雷达的拆收和架设速度。过去，雷达天线车大多数采用手工调平，升降速度慢、调平精度差，阵面起竖系统复杂，费时费力。本文中设计完成的某雷达的技术特点及环境条件要求，参考和借鉴国内外在雷达天线升降技术和方法，大大缩短了雷达的拆、装时间，改善了雷达的机动性能。本文还在雷达总体布局、工作可靠性、维修可达性和安全性设计等方面作一定研究，论证了此设计方案的可实施性和优越性，为其他型号车载雷达升降系统的设计与研究奠定了基础。

 Radar antenna automatic lifting mechanism

   I graduated from the current design is done mainly hydraulic lifts, mainly divided into two parts: mechanical and hydraulic parts. Mechanical parts which I think the main needs to be considered is the subject of several major part of the intensity: on board planes, under the board planes, within and outside link connecting rod. In this part of my four were on board from top to bottom-line Analysis of the internal and external linkage, I had the strength check. After my analysis and after checking I think I can satisfy the design requirements. Then I entered the various parts of the hydraulic choice. In the choice of the hydraulic control circuit all the time, in the loop on a comparison of the governor after I selected the import speed loop circuit; unloading loop I chose the valve of the unloading circuit; packing circuit I have chosen The use of one-way valve controlling the packing circuit. In determining the needs of the various circuit I, I'm sure I wear the hydraulic system of fixed form, according to open-system and the system simple cooling system features good condition, I set my drive system for open - System. On the other hydraulic components accessories choice, I had to them after the calculation of the hydraulic cylinders after I voted 45 mm of hydraulic cylinders, according to the transmission gear pump stability, I take my pump as a gear Pump, according to my system the maximum power of the work I elected to the motor Y112M-4 to three-phase asynchronous motor. I set the pump, I also based on this I need the yuan other accessories for a reasonable Choose, finally, I identified a variety of components, further complete the design of the topics I.
