摘要
某些复杂工业产品用确定性模型进行系统设计,QMU是近几年提出的源自确定性模型的系统认证新方法,它能够在综合利用试验信息和数值模拟信息的基础上,有效揭示失效模式并以简捷的信息结构对系统的综合效能做出合理的评价和认证。QMU正在快速发展并引起了美国重要技术部门的重视,但目前很少见到公开的应用实例。本文以可靠性物理和计算科学为背景论述QMU的基本思想和实现途径,并探讨QMU在不同工程问题中的使用方法以及对QMU起支撑作用的信息处理和V&V技术。
Some complicated industrial products are designed with deterministic models. As a newly presented certifying method which is subject to deterministic model, QMU is able to efficiently reveal the failure models and give a brief formula in assessment with the combined information of tests and numerical simulations. QMU has now been developed quickly and attached significance to some US Departments, but the idiographic ways to fulfill QMU are not in public. Based on reliability physics and computational science, the basic ideas of QMU as well as its implementations in different engineering problems and the supporting technologies such as info-theory and V＆V are mentioned aiming to form a unified QMU certification for integrated systems.
