摘要: 面向在轨伸出式靠泊加注任务,针对对接过程中加注管路因同步外伸而产生附加力的问题,提出了一种偏置椭圆螺旋构型的加注管路。首先,推导了管路的轴向刚度和应力数学表达式,通过有限元仿真和实验校验了上述两个表达式的准确性。之后,将偏置椭圆螺旋管路与其他三种适用管路在同一设计空间下分别进行了基于最小轴向刚度的构型优化设计,得到了上述四种管路各自的最优构型与最小附加力,形成了该类在轨加注螺旋管路的完整设计方法。与仿真和实验结果对比,所推导的管路轴向刚度与应力数学表达式的相对误差均小于5%,可用于该类管路的设计分析。与无偏圆螺旋管路相比,所提出的偏置椭圆螺旋管路将靠泊加注对接过程中的管路附加力降低了约83.5%,更适用于在轨靠泊加注任务。

Abstract: For the on orbit stretching berthing refueling task, a bias loading elliptical helical pipeline configuration is proposed to solve the problem of additional force caused by synchronous extension of the refueling pipeline in the docking process. Firstly, the axial stiffness and stress mathematical expression of the pipeline are deduced, and the accuracy of the above two expressions is verified by finite element simulation and experiments. Then, the configuration optimization design based on the minimum axial stiffness is carried out for the elliptical helical pipeline and the other three applicable pipelines in the same design space. The optimal configuration and minimum additional force of the above four pipelines are obtained, and the complete design method of this kind of on orbit refueling pipeline is formed. Compared with the finite element simulation and experimental results, the relative errors of the derived mathematical expressions of the axial stiffness and stress of the pipeline are less than 5%, which can be used for the design and analysis of this kind of pipeline. Compared with the unbiased circular helical pipeline, the proposed bias loading elliptical helical pipeline reduces the additional force of the pipeline by about 83.5% during the docking process, which is more suitable for the on orbit berthing refueling task.
