可靠性工程中自然环境条件量化分析数据库构想

摘要

在可靠性工程应用中,基于失效物理的分析过程需要引入自然环境数据进行仿真计算.首先对比分析了现有自然环境数据库,明确了新开发的数据库的需求与特点；然后提出了在自然环境条件量化分析数据库研发过程中的关键技术；最后,通过一个应用算例演示数据库的运行过程.该数据库目前已具备一定的通用分析能力和工程应用价值.%In engineering applications, it is necessary for reliability analysis based on physics-of-failure to introduce natural environmental data into simulated calculation. The existing databases of natural environment were compared, and the needs and characteristics of new database were determined. The key techniques in the research and development process were proposed. The database operation was demonstrated by an example. The new database was provided with general analytic functions and engineering application value.
