Abstract: The finite element analysis software ANSYS can be used to establish the finite element model of antenna and receiver mechanism of micro wave humidity sounder of FY3 satellite and to obtain the response characteristic of the finite element model which was stimulated by harmonic loads in x, y and z direction respectively. Judged by the displacement response data of each monitored point, the conclusion that the mechanism is eligible under the load case of harmonic loads is drawn.

Key words: finite element, satellite, humidity sounder, harmonic response
