【摘要】：可靠性指产品在规定条件下和规定时间内,完成规定功能的能力。产品可以泛指任何系统、设备和元器件。可靠性分析计算是比较复杂的,其方法种类繁多,目前没有一个固定的方法和流程。由于可靠性计算涉及的分析软件众多,开发集成度高的可靠性计算辅助工具是非常重要的,可靠性设计人员无需对复杂可靠性几何模型进行深入了解,只需输入相关参数,减轻了设计人员的负担。本文以机电组件结构性能与可靠性分析项目为依托工程,研发了面向振动和温变环境的可靠性计算平台,首先简单介绍了国内外可靠性工程发展现状、发展趋势及存在的问题,然后针对机电组件可靠性分析流程,对可靠性计算平台进行了需求分析、架构设计及功能模块设计,确定了计算平台的总体设计方案。详细介绍了可靠性计算平台开发的关键技术,即ANSYS和Matlab二次开发集成,在ANSYS二次开发集成过程中采取参数化设计语言技术实现整个建模分析等结构分析流程,在Matalb二次开发集成过程中采取动态链接库技术实现可靠性计算。在Visual Studio 2010统一架构下,将结构分析软件和数值计算软件集成,从建立几何模型、材料属性、网格密度划分等建模过程到施加载荷分析过程,形成一个固定的方法和流程,计算经验得到很好地保存,同时对技术人员的软件熟悉要求降低,只需通过用户界面形象直观查看结果或操作模型,实现可视化技术。数据库能够储存庞大数据,方便可靠性计算,工作的系统性增强。异构软件的集成在一定程度上缩短可靠性计算周期,操作简单,提高工作效率。
[Abstract]:Reliability refers to the ability of a product to complete a specified function under specified conditions and within a specified time. Products can refer to any system, equipment, and components in general. Reliability analysis and calculation are complicated, and there are many kinds of methods, so there is no fixed method and flow at present. Because there are many analysis software involved in reliability calculation, it is very important to develop a highly integrated reliability calculation assistant tool. The reliability designer does not need to deeply understand the complex reliability geometry model, but only needs to input the relevant parameters. It lightens the burden on designers. In this paper, based on the project of structural performance and reliability analysis of electromechanical components, a reliability computing platform for vibration and temperature change environment is developed. Firstly, the development status, development trend and existing problems of reliability engineering at home and abroad are briefly introduced. Then, according to the reliability analysis flow of electromechanical components, the requirement analysis, architecture design and function module design of the reliability computing platform are carried out, and the overall design scheme of the computing platform is determined. The key technology of reliability computing platform development is introduced in detail, that is, ANSYS and Matlab secondary development integration. In the process of ANSYS secondary development and integration, parameterized design language technology is adopted to realize the whole modeling and analysis process. In the process of Matalb secondary development and integration, dynamic link library technology is adopted to realize reliability calculation. Under the unified framework of Visual Studio 2010, the structural analysis software and the numerical calculation software are integrated, from the modeling process of building geometric model, material properties, grid density partition and so on, to the process of applying load analysis, forming a fixed method and flow. The calculation experience is saved well and the requirement of familiarity with the software of technicians is reduced. The visualization technology is realized only by viewing the result or operation model intuitively through the user interface image. Database can store huge data, convenient reliability calculation, systematic enhancement of work. To some extent, the integration of heterogeneous software shortens the period of reliability calculation, easy to operate and improves working efficiency.
