飞行器地面试验评价方法研究

Research on AerocraftGround Experiment Evaluation Technology

摘要:

摘要：为进一步提高飞行器的地面试验效能，提出了一种基于试验建模的飞行器地面试验评价体系，包括地面试验过程建模和适用度评价方法研究两个步骤，针对试验需求与目标、试验任务、试验过程、试验资源、试验场、试验结果等六个试验环节，进行基于UML机制的建模技术研究，建模工具选择美国Rational公司的面向对象的可视化建模工具RationalRose，通过“蛛网图”评价、灰色关联分析和基准评价三种评价方法对试验模型进行了适用度指标评价研究, 通过适用度评价指标选出较优化的试验方案。结合某飞行器地面点火试验方案，构建了基于试验建模的试验评价体系，对试验过程、试验方法、试验手段、试验数据等，根据适用度评价方法进行了试验方案最优化研究应用，取得了良好的验证效果。

Abstract:

Abstract：In order to improve aerocraft’s ground test efficiency, an aerocraft ground test evaluation system based on test modeling was developed. The system had two procedures, test modeling and relevance evaluation. In view of six test elements including experiment demand and goals, assignment, procedures, resources, facility and results, research on modeling technology based on UML mechanism was carried out，and the modeling tools was RationalRose, an object-oriented visual modeling tool of Rational companies in the United States. According to three evaluation methods as spider net evaluation, gray relative analysis and reference evaluation, application of the test model is studied, and the better test plan was selected by comparing the evaluation index. Combined with an aircraft ground ignition test scheme, the application of test evaluation system based on the ground ignition test modeling was constructed. Around the test process, method, data and so on, the application was verified and good results were achieved.
