基于公理设计的产品可靠性要求实现方法

针对可靠性设计要求难以系统、全面落实到产品设计方案的问题，提出了一种基于公理设计的产品可靠性要求实现方法.首先，应用公理设计原理进行产品初步设计，从而确定其功能需求，并针对各项功能的保持要求进一步扩展功能保持需求（扩展的功能保持需求构成功能保持域，该域包含于功能域），进而系统导出参数化的可靠性设计方案；其次，根据功能保持需求扩展或优化设计参数，构建考虑可靠性设计要求的域映射模型，并给出应用独立公理进行方案评价的方法.同时，以温度传感器设计为例贯穿全文，验证了所提出方法的可行性和有效性.

Design-in of reliability through axiomatic design

To completely meet the requirements of reliability design in the product designing, an axiom-based designing-in reliability approach was proposed. In light of the axiomatic design principles, products were designed preliminarily to establish their functional requirements, so that according to these the preservation requirements were augmented (the functions preserving requirements constitute a functional requirement preserving domain that is included in functional domain), which derived the parameterized solution for reliability design systematically. Subsequently, the design parameters were augmented and optimized to achieve the functions preserving requirements. Mapping model of the augmented functional domain, the physical domain was established. And a solutions evaluation approach based on independence axiom was proposed. Being exemplified by the design of a temperature sensor, the present study demonstrates that all approaches are feasible, efficient, and could be applied in real engineering scenarios.
