阿里原初引力波探测望远镜的三轴转台设计
|
摘要
为了得到高精度的北天区原初引力波极化数据,需在西藏阿里地区建设原初引力波探测望远镜。针对望远镜的观测要求,设计了一种三轴转动平台。对转台各组成部分的结构设计进行了详细介绍,同时给出了载荷计算和驱动电机的选型过程,对转台进行了力学仿真分析,对影响望远镜指向精度的误差源进行了辨识并合理分配,保证设计制造满足指向精度的要求。
In order to obtain high-precision polarization data of the original gravitational wave in north district,an original gravitational wave exploration telescope is designed to build in the Ali area of Tibet.According to the observation requirements of the telescope,a three-axis turntable is designed.The structural design of each component of turntable is introduced in detail,the process of load calculation and drive motor selection is given,and the mechanical simulation analysis of turntable is carried out.Finally,the error source that affects the telescope pointing accuracy is identified and reasonably distributed to ensure that the design and manufacture meet the pointing accuracy requirements.
