摘要

为了满足日益增长的通信需求,卫星需要配备高精度、大口径的天线。在轨装配技术是构建高精度超大口径模块化天线的有效方法之一。在轨装配任务中,装配误差是影响模块化天线表面精度的关键因素。本文研究了各模块的节点设计和模块天线的装配误差分析。提出了一种考虑模块间装配间隙的模块节点设计方法。同时,设计了软连接机制,保证了装配模块之间的可移动性。为了研究装配误差的传递规律,建立了基于指数积方法的装配误差解析模型。为了建立具有旋转和位移装配误差的变形面,通过解析模型提出了误差球的概念。为了减小装配误差,将执行机构安装在各个模块之间。此外,还提出了一种获取执行机构调整量的方法。最后,通过数值模拟验证了解析模型的正确性和调整方法的有效性。

Analytical method for computing assembly errors in modular antenna during on-orbit assembly
To meet the increasing communication demands, the satellites need to be equipped with the high-accuracy and large-aperture antennas. One of the effective methods to construct the modular antennas with ultra-high accuracy and ultra-large aperture is on-orbit assembly technology. During the on-orbit assembly missions, the assembly error is a key factor to affect the surface accuracy of the modular antennas. This paper studies the node design of each module and the assembly error analysis of the modular antennas. A design method of the module nodes is presented with consideration of the assembly gap between two modules. Meanwhile, a soft connection mechanism is designed to ensure the mobility among the assembly modules. To investigate the transmission law of the assembly errors, an analytical model of assembly error is derived based on the exponential product method. In order to establish the deformation surface with rotation and displacement assembly errors, an error ball concept is proposed by the analytical model. To decrease the assembly errors, the actuators are installed among some modules. Moreover, an adjustment method is proposed to obtain the adjustment amounts of actuators. Finally, the correctness of analytical model and the effectiveness of the adjustment method are demonstrated by the numerical simulations.
