摘　　要：空间站是在运载包络、上升段力学环境、空间环境、在轨维修、天地备件保障等诸多工程约束条件下,首次系统开展维修性设计的载人航天器,其最重要的特点是以可靠性为中心的在线维修,维修过程中空间站平台须正常在轨飞行.通过开展维修可视可达、故障隔离、维修工作模式、维修影响域最小化、产品通用化、接口标准化、维修风险控制等设计,实现了空间站在轨可维修.通过构建数字化仿真模型,提高了维修性设计的准确性和效率.空间站在轨关键技术验证阶段,开展了维修性在轨实践,初步验证了空间站维修性设计方法的正确性.The space station is the first maintainable manned spacecraft designed under many engineering constraints,such as launch envelope,mechanical environment,space environment,on-orbit repair,and spare parts support.Its most important feature is reliability-centered online maintenance.During the maintenance,the space station normally remains in orbit.Through the design of visual accessibility,fault isolation,working mode,minimization of influence area,product generalization,interface standardization,and risk control,the space station can be maintained in orbit.By building a digital simulation model,the accuracy and efficiency of the maintainability design are improved.In the key technology verification stage of the China space station,the on-orbit maintainability practice was conducted,preliminarily verifying the precision of the maintainability design method of the space station.
