航天器在轨服务捕获装置技术研究综述与展望

空间捕获装置是航天器在轨服务与维护任务的重要末端执行器，承担着捕获包括航天器、舱段、空间碎片及实验样品等多种目标的任务。根据被捕获目标的性质可以将捕获装置分为合作目标捕获装置和非合作目标捕获装置2大类。在捕获装置设计过程中，捕获目标是否具有特定的抓持结构则是捕获装置机构形式设计的先导因素，根据捕获目标是否具有特定的抓持结构，可以将捕获装置分为基于抓持结构的捕获装置以及非基于抓持结构的捕获装置。以捕获装置工作原理与捕获目标类型为分类依据，对捕获装置进行分类，分别阐述了其技术原理与关键技术，并对各类捕获装置进行了对比分析，根据分析结果指出了捕获装置未来的发展方向。     

Optimal planning for a multi-debris active removal mission with a partial debris capture strategy

In this paper, a new mission model, called a multi-debris active removal mission with partial debris capture strategy, is proposed. The model assumes that a platform only captures part of the scheduled debris at a time and then releases these debris pieces to a disposal orbit. This process is then repeated until all of the scheduled debris is removed. A genetic algorithm with a multiparameter concatenated coding method is designed to optimize the plan of a multi-debris active removal mission wit...     

Collaborative manufacturing technologies of structure shape and surface integrity for complex thin-walled components of aero-engine: Status,challenge and tendency

Presently, the service performance of new-generation high-tech equipment is directly affected by the manufacturing quality of complex thin-walled components. A high-efficiency and quality manufacturing of these complex thin-walled components creates a bottleneck that needs to be solved urgently in machinery manufacturing. To address this problem, the collaborative manufacturing of structure shape and surface integrity has emerged as a new process that can shorten processing cycles, improve machining qualities, and reduce costs. This paper summarises the research status on the material removal mechanism, precision control of structure shape, machined surface integrity control and intelligent process control technology of complex thin-walled components. Numerous solutions and technical approaches are then put forward to solve the critical problems in the high-performance manufacturing of complex thin-wall components. The development status, challenge and tendency of collaborative manufacturing technologies in the high-efficiency and quality manufacturing of complex thin-wall components is also discussed.
