摘要
“材料应用验证”是为适应复杂工程研制任务而建立的一种材料多参数指标在特定服役需求下应用适用度评估的综合评价方法,也是通过一系列的试验、测试与表征手段获得材料各项性能数据、曲线、图谱,并通过综合分析确定材料应用可行性的分析方法。文章从航天器发展对高性能、多样化材料快速应用转化需求出发,阐释材料应用验证任务具有指标体系的综合性、通用性、短周期、低成本以及闭环式验证特点,进而提出了覆盖性、关重性、精准性、独立性、经济性的指标体系设计原则,以及材料应用验证的三层级五要素即材料批次稳定性、工艺适用性、环境适应性、服役安全性及组件健壮性指标体系设计及优化方法。
Material application verification is a comprehensive evaluation method,which is established to evaluate the application suitability of material multi-parameter indexes under the specific service requirements,for adapting to the complex engineering tasks.Various performance data,curves and maps of materials are obtained by a series of tests and characterization methods,and through comprehensive analysis,the feasibility of material application process are determined.Based on the requirements of high-performance materials,diversified materials and rapid application of materials for spacecraft development,this paper explains that the verification task of materials application is characterized by comprehensiveness,generality,short period,low cost and closed-loop verification of the index system.According to these characteristics,the index system design principles of coverage,criticality,accuracy,independence and economy are proposed,as well as the design and optimization methos of the three-level and five-factor index system of material application verification,including batch stability,process applicability,environmental adaptability,service safety and component robustness,are proposed.
