摘要
产品的工作环境是影响产品可靠性的关键因素之一。任何一种产品都处在一定的环境之中,同时要在一定的环境中贮存、运输和使用,因此其使用可靠性与这些环境因素密切相关。产品的环境适应性从产品的设计、研发、生产就已经定好了,而产品耐环境则是通过相关标准规范进行试验而得出的,只有通过环境考核的产品,其使用可靠性才能得到保障。本文首先介绍不同环境应力对产品的影响以及会引发何种失效模式;随后介绍,如何获得产品的使用环境;最后说明为保证产品的环境适应性以及可靠性,如何选择标准以及不同标准对产品的环境适应性的考核要求。通过对产品工作环境的影响分析及标准的测试方法及要求,为产品进行环境适应性试验设计提供参考。
The working environment of the product is one of the key factors affecting the reliability of the product.Any kind of product is in a certain environment,and it must be stored,transported and used in a certain environment,so its use reliability is closely related to these environmental factors.The environmental adaptability of the product has been set from the product design,research and development,production,and the product environmental resistance is tested through relevant standards and specifications,and only through the environmental assessment of the product,its use reliability can be guaranteed.This paper first introduces the effects of different environmental stresses on products and what failure modes will be caused.Then it introduces how to obtain the use environment of the product;Finally,in order to ensure the environmental adaptability and reliability of the product,how to choose the standard and the assessment requirements of different standards on the environmental adaptability of the product are explained.Through the analysis of the impact on the working environment of the product and the standard test methods and requirements,the reference is provided for the environmental adaptability te st design of the product.
