摘要
精密跟踪转台是高精度飞秒激光跟踪仪的关键单元,其精度直接影响激光跟踪测量系统的总体精度,而跟踪转台的精度主要由轴系精度决定,因此跟踪转台的轴系结构设计以及对其轴系进行性能分析非常重要。文中首先对精密跟踪转台进行结构设计与建模,利用SAMCEF of rotor软件对二维转台2个轴系进行了仿真分析。根据激光跟踪仪性能要求与仿真结果对轴系结构进行分析与优化。最后通过搭建的二维转台验证了所设计轴系的可行性,能够满足激光跟踪仪跟踪转台高精度、高灵敏度和低跳动的要求。
The precision tracking turntable is the key unit in the high precision femtosecond laser tracker,and its accuracy di- rectly influences the general accuracy of laser tracker system and depends on that of axis.Consequently,the design and analysis of axis structure in tracking turntable ale important. In this paper,structure design and modeling of the precision tracking turntable were firstly designed,and then the software SAMCEF of rotor was applied to analyze the two axis of 2D turntable axis.Based on the property requirements and simulation results of laser tracker,the axis systems were analyzed and optimized.Finally, the 2D turntable was designed to validate the feasibility of the axis system, which can meet the requirements of high precision, high sensitivity and low jitter of laser tracker.
