Research on the Wind-load Stress of a Working Vehicle-borne Weather Radar Antenna

The traditional examination method is carried on the experiment in the wind tunnel to solve the problem of destruction and destabilization which possibly occur to radar antenna in active status under the wind-load condition.This method spent too much money and time.The empirical datum gathers difficultly.It is disadvantageous to design,manufacture,and use for the radar.we carried out analysis and comparison to the distortion,stress and strain of radar antenna under different wind-load using finite element analysis(FEA) software ANSYS.Compares the traditional method,it is more quickly,economy and actual.This will provide theory support for the reliable application of radar antenna under different wind-load condition,and offer lessons to the structure optimization of radar antenna.
