摘要
对某深空探测器中的有效载荷——高精度磁强计的安装部件进行了有限元分析,分别获取了磁强计安装部件在升空过程中承受40g加速度冲击载荷以及-180～75℃的极限温度情况下,在x,y,z方向上的最大应力和最大位移,给出了由于磁强计安装部件的变形而导致的三个探头在x,y,z方向上的偏转角度,采用扫频实验法分析了磁强计安装部件的频谱特性,为空间探测磁强计的设计提供了依据.
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 -180℃to 75℃,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.
