The Auto-erecting System Design Of A Mobility Meter Band Wave Radar

Since the birth of radar in WW II,After nearly 80 years of development,Radar is widely used in intelligence,anti-missile,electronic countermeasures,telemetry,and atmosphere field as an electronic equipment.By the stealth aircraft appears,meter band wave radar with anti-stealth technology caused the high attention of the countries all over the word.The new situation and requirement of the modern war,the fast-reaction capacity design of radar mobile disposition is very important.So erection and withdrawal design is an important topic in radar engineering.but the space and weight restrictions make the contradictions between the large antenna caliber,high gain and precision.The erection and withdrawal design is the key technology of the mobility radar development.The project background of this paper is a new three-dimensional MBR(meter wave band radar),the subject comes from the project in the key technology:16 persons should erect and withdraw the whole radar within 1 hours.Compared with conventional radar,the structure of the antenna is more complex than that of conventional radar,the transmitting and receiving electronic equipment are installed in the antenna structure,auto-folding and un-folding design is very difficult and the working environment is more hard,so the technical requirements is very hard to realise.In this paper,according to the requirement of the radra,Introduced the general design and the major components of the radar,Submit the design project of the erceting mechanical structure and the hydraulic systems.By means of the Virtual Prototyping Technology and the theory of structural analysis,the main technical indexes has meet the requirements.With MSC.Adams and LMS Imagine.lab AMESim software,The simulation analysis model of the hydraulic lifting mechanism of radar antenna is built to carry on the dynamic analysis then taking the hinge points of the hydraulic cylinder as design variables and objective functions is also set in the Adams,and uses the experimental design method has carried on the simulation to institutions.
