Abstract: Finite element technique is utilized to analyze payload of the detector, which is the high precision magnetometer structure component. When the magnetometer structure component bears impact load of 40 g in the blastoff process and simultaneously bears extreme temperature ranging from -180ºC to 75ºC, the maximum stress and displacement are respectively obtained in the directions of x, y and z. Moreover, due to the deformed magnetometer structure component, deflective angles of three probes are also obtained in the three directions. Finally, the sweep experiment is utilized to analyze spectrum characteristics of the magnetometer structure component, and the objective of experimental date has been obtained. It verifies the dynamic characteristics of the magnetometer structure component and provides technical support for the space-borne magnetometer designing.
