[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.
