航天器数字化测试模式设计与应用

Design and Application of Spacecraft Digital Test Mode

随着航天事业的发展,航天器将迎来高密度的研制和发射任务;测试设计和实施同步、测试现场消耗大的测试模式导致测试效率低下,不能满足未来的综合测试需求;为解决航天器测试效率不能适应测试任务的问题,设计了航天器数字化测试模式;搭建数字化测试平台,实现测试准备、测试实施、测试评估全周期自动化;基于数字化测试平台,开展综合测试专业化设计与实施;推进测试设计与测试实施分离,将测试设计工作前移,测试设计人员通过测试用例与测试判据的精细化设计,将测试准备工作做充分,实现测试实施和评估过程自动化;数字化测试模式应用于多个航天器型号综合测试,形成多个固化测试用例数据库,有效提升测试效率,为后续型号测试能力的提升奠定坚实的基础。

With the development of space industry, the spacecraft will have a high density of development and launch mission. Low test efficiency can not meet the needs of integrated testing in the future because of large test patterns and synchronization between test design and implementation. To solving the problem of collision between inefficient test and high--frequency spacecraft design and launch missions, dig ital test mode is proposed. Digital te^t paltf0rm is built to achieve full cycle automation of test preparation, test implementation and testing e- valuation. Based on the digital test platform, test specialized design and implementation is carried out. Pushing test design apart from test implement, test design is moved forward. Through subtly design of test case and criterion, test provision is well prepared, and the automation of test implement and evaluation is realized. Digital test mode has carried out in multiple spacecraft test, a number of curing test case database is formed. The test mode bring out effectively test improvement, and lay a solid foundation for the follow--up model test ability.
