| 目的 研究提出基于分档策略的装备统一环境试验条件设计方法。方法 首先，对装备力、热、自然等环境试验条件的统一化进行详细论证，研究得到不同类型环境条件的分档策略。然后，对不同型号环境试验条件的项目进行分析，提出环境试验项目“基本项”+“定制项”的统一方法，得到通用试验项目和定制试验项目。随后，对于特定环境试验项目，提出基于极值的“包络式”、基于概率统计的“精细式”和基于就近归集的“分档式”3种统一环境试验条件制定方法，给出各种方法的特点、剪裁方法，并结合典型航天型号，给出应用案例和方法示意。结果 得到了基于分档策略的装备统一环境条件制定的方法，给出了典型装备的分档环境试验条件。结论 从装备的实际出发，提出的基于分档策略的装备统一环境试验条件的设计方法，经实践证明是可行的，对于降低货架产品的研制、批产和验收成本具有重要工程意义，并且对于其他类型产品的技术条件统一化具有重要的借鉴意义。 |

| The work aims to propose a design method of unified environmental test conditions for equipment based on grading strategy. First of all, the unification of mechanical environment, thermal environment, natural environment and other environmental test conditions of equipment were demonstrated in detail, and the grading strategies of different types of environmental conditions were obtained. Then, the items in different types of environmental test conditions were analyzed, the unified method of "basic item" + "customized item" of environmental test project was put forward, and the general test project and customized test project were obtained. Then, for specific environmental test projects, three unified environmental test conditions were proposed:"envelope" based on extreme value, "fine" based on probability and statistics, and "grading" based on nearest set. Finally, the characteristics and tailoring methods of various methods were given, and the application cases and methods were displayed in combination with typical aerospace models. Thus, the method of establishing unified environmental conditions of equipment based on grading strategy was obtained, and the grading environmental test conditions of typical equipment were given. Considering the reality of equipment, the design method of unified environmental test conditions for equipment based on grading strategy is proved to be feasible, and it is of great engineering significance to reduce the cost of development, batch production and acceptance of shelf products and has important reference significance for the unification of technical conditions of other types of products. |
