【Abstract】 The weight of the manned spacecraft system often exceeds the standard at the initial stage of the plan and frequent design iterations are required. To solve this problem, the control link of the product weight design was determined based on the system design and development process, then the physical weight data of Shenzhou spacecraft, Tianzhou spacecraft and China Space Station during the assembly and construction phase of the space station were systematically studied. In addition, the theoretical method of successful envelope analysis was adopted and a quantitative evaluation model was established to guide the quality of the product weight design. It can be used to guide the decomposition and distribution of product weight indicators at all levels at the initial stage of the system design, and to guide the iterative optimization of product weight at the end of the system design, thus to reduce the system design iterations and improve the capacity of system equipment.更多还原
