本设计是根据国内外雷达车的发展趋势,通用性、适应性以及稳定性不断提高,本着结构简单、操作灵活的原则,而设计的一种能同时完成调节水平、自动举升的雷达车。本文具体阐述了一种车载装置升降系统的设计和开发过程。本课题所研制的车载装置升降系统可以实现预期的雷达的举升和下降。在自动调平系统工作结束以后,通过设计的举升液压缸的伸出和缩回,带动塔架的举升和下降,从而实现雷达的举升和下降。同时设计过程中考虑了整个雷达受到本身重力和风力的影响,着重对稳定性以及适应性进行设计选择。 关键词:液压缸;雷达;自动调平系统本科毕业设计(论文)通过答辩

II Abstract The design is based on the development radar vehicle in and out country, interoperability,adaptability and stability in a constantly improving the structure and operation of flexible simple principles designed to simultaneously accomplish a radar vehicle which is complete adjust level, automatic lifting.The topic of my paper is vehicle-mounted machine automatically transferred Ping mechanical systems design and development.This topic the on-board device developed lifting system can achieve the desired radar lifting and decline.In automatic levelling system through the design work finished, the lifting hydraulic cylinder of reaching out and retract, driving the tower lifting and falling, thus realize the lifting and decline.Meanwhile the design process by considering the whole radar the influence of gravity and wind itself, focuses on the design choices stability and the adaptability.
