摘要
与电子产品相比,焊接结构有许多不同点:失效模式复杂;以耗损型故障为主;大多是专用件,标准件少;数据缺乏。因而,机械产品可靠性无法像电子产品那样,通过查询标准数据手册获得。该文基于应力-强度干涉模型,使用一次二阶矩法对焊接结构的可靠性进行计算。
Compared with the electronic products,there are many different characteristics of the reliability of welding structures：the failure mode is complex;mainly wear fault;mostly special parts and few standard parts;lack of data.As a result,the reliability of welding structures cannot be obtained by referring to standard data manual.In this paper,based on the stress-strength interference model,we use first order second moment method to calculate the reliability of the welding structures.
