摘　　要：利用大型有限元分析软件ANSYS建立FY-3卫星微波湿度计天线与接收机单元的有限元模型,通过在x,y,z3个方向上分别施加基础正弦激励,获得有限元模型在不同加载方式下的响应.通过提取各监测点的位移响应,得出了结构在正弦激励试验下是合格的结论.The finite element analysis software ANSYS can be used to establish the finite element model of \{antenna\} and receiver mechanism of microwave 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.
