面向虚拟试验的可信度评估工具设计与实现

Design and Implementation of a Reliability Evaluating Tool in Virtual Test

虚拟试验技术在航天领域得到了越来越广泛的应用,尤其是在多专业耦合仿真方面,但是面向虚拟试验的可信度评估工具方面的建设与研究未得到充分关注;针对虚拟试验分析阶段的工程需求,设计并实现了虚拟试验可信度评估工具,涵盖了评估对象管理、评估专家管理、指标体系构建、可信度评估等功能模块;此外,该工具还提供了虚拟试验与实物试验的数据库接口,有效地支撑了虚实比对工作,进一步规范了虚拟试验的分析流程与分析内容,有效提升了工作效率。

Virtual test techniques have been more and more widely utilized in the aerospace field, especially about multidisciplinary coupling simulation. However, the study on reliability evaluating tool has not been paid enough attention to in virtual test. In consideration of the engineering requirement during test analyzing phase, we have designed and implemented a reliability evaluating tool, which includes funetional modules like evaluating-objects management, evaluating-expertsmanagement, index-systemconstruction. Moreover, it offers in- terraces to virtual test and physical test databases, which effectively helps the contrast work between the two tests, standardizes the analyzing flow and content of virtual test, and highlights the work efficiency.
