摘要
在产品设计阶段进行测试性设计可提高产品的固有测试性,基于多信号流图的测试性设计方法是复杂系统测试性设计的重要手段。使用该方法,以一型号载人航天器供电系统为研究对象,对其进行建模、分析和优化。仿真结果表明:该方法可以提高供电系统的故障检测率和隔离率,减小模糊组大小,优化后供电系统的测试性设计品质参数得到了提高。
Testability design can improve the inherent testability of product. The design method based on multi-signal flow diagram is an important approach for the testability design of complex system. This method is used in the testability design for the power supply system of a certain manned spacecraft. Results of modeling and optimization show that this method can improve the fault detection rate and fault isolation rate of the power supply system, while at the same time reduce the size of the fuzzy group. The testability design quality parameters of the optimized power supply system have been improved.
