| 摘 要： | 中国月震计宜于采用MEMS加速度计作为拾震传感器,以满足对重量、体积、功耗和可靠性等方面的要求.在无人登月探测中,为免使月震计的投放装置过于复杂,也为减小月震计系统的重量、体积和功耗,以及增加系统工作的稳定性和可靠性,不给月震计增加机械的水平和定向调节装置,本文根据机器人理论,通过旋转变换,论证了可以从倾斜、非定向安装的月震计观测到的月震波得到以月球北极为参考方向的水平坐标系的观测,并从实验上作了部分验证,从而为这一难题的解决找到一条可行的探索途径.

| Abstract: | It is difficult to insure that the moon seismometer placed by a robot is horizontal, and it is also difficult to add a mechanical horizontal and directional controller for the moon seismometer because of the restrictions of its weight, size and so on. To resolve this problem, according to the robotic theory, the paper suggests to get the moonquake waves in the horizontal plane coordinate in which the reference direction is the north pole of the moon by coordinate rotation transforming from the moonquake wave measured in the oblique coordinate. |
