车载雷达液压升降系统设计

车载雷达液压升级系统设计

摘要

随着国际形势的动荡，局部战争的不断爆发，现代武器装备的不断更新，现代战争已进入了电子战，信息战时代，传统的机动型雷达已经不能满足现代战争的需要。各国为了提高自己的防卫，跟踪，识别和反击能力，高机动地面雷达应运而生。

天线快速，可靠地机动架设和撤收是车载雷达的基本要求之一。按传动系统的不同，雷达天线升降机构可分为机电式和液压式。与机电式相比，在输出同样功率的条件下，液压式的体积和质量小，承载能力大，可以完成较大重量雷达天线的架设，还可大大简化机械结构，减少机械零部件的数目，也便于实现自动控制。随着科技的发展，液压式传动系统已逐渐在雷达天线升降机构中被采用。本设计采用一种翻转式液压举升机构及其液压系统，可实现对较大型天线的高架，并且在天线的举升过程中，天线的姿态不变，架撤收过程平稳，可靠，快速

The design of car radar hydraulic upgrade system

Abtract

Turmoil as the international situation, local wars breaking out, constantly updated, modern weapons and equipment of modern warfare has entered the electronic warfare, information warfare era, the traditional mobile radar can not meet the needs of modern warfare. Countries in order to improve their defense, tracking, identification, and fight back ability, high-motorized ground radar came into being.

Fast, reliable motorized antenna erection and dismantling is one of the basic requirements of the automotive radar. For differences in the transmission system, the radar antenna lifting mechanism can be divided into electro-mechanical and hydraulic. With electromechanical compared to the same output power conditions, the hydraulic volume and mass of small carrying capacity, the larger weight of the radar antenna can be completed erection, but also greatly simplifies the mechanical structure, reducing the number of mechanical parts, also easy to achieve automatic control. With the development of science and technology, the hydraulic drive system has been gradually the radar antenna lifting mechanism is used. This design uses a flip-hydraulic lifting mechanism and its hydraulic system, can be elevated to the larger antenna, and in the process of lifting of the antenna, the antenna of the same attitude, erecting the closing process is smooth, reliable, fast
